Better?


So you are a genius with a disability, then?


Some tried to tell me that. But I don't see it since some simple tasks
are very difficult. And for me, it is grammar. And I used to stutter
until my late teens. Oddly enough it seemed to stop after my first beer.
Surely just a coincidence, right? LOL

So far I don't see it. Thanks for the lecture, I will not say
anything about the grammar flukes in the future.


No that is okay. I am used to it and it isn't any big deal. ;-)

It's also difficult to speculate whether these people were
accomplished because of their disability, or in spite of it.
People with other types of handicaps were also great achievers.


Well from my perspective, it is very easy to identify with. As *some*
simple tasks are difficult and *some* supposedly hard tasks are simple.
So it makes sense that they would excel in areas that they find very
easy to understand. Although they still have to struggle with some
supposedly easy tasks. :-(

strange way you come across at times. *L*

I have been busy since posting the question so I haven't had an

maybe 15 to 45 minutes into playing an AVI file.

I tried VLC, Windows Media Player, and DivX player. All of them put
garbage in the window in pivoted mode. Only Nero ShowTime actually
makes a viewable image in pivoted mode. Suggestions for other players?

The 'medium-high-pitched' sound is somewhere in the 500-1000Hz range.
I didn't try to check it when the glitch happened -- I just wanted to

maybe coming from the speakers. I didn't check that either.

The really odd thing is the glitch's effect on CPU hyper-threading. I
can conceive of it disabling hyper-threading but I don't understand
why hyper-threading is not re-enabled after a hardware reset and
reboot (as evidenced by the BIOS Setup), and even the first time the
system goes into Windows (as evidenced by Task Manager), but it is
enabled after going into Windows a second time. Hyper-threading is not
only disabled: the line in the BIOS Setup screen does not even appear,
as if the CPU does not have hyper-threading capability, until the
system has gone into Windows once and then restarted a second time.

I experimented a little more tonight. I played an AVI file in pivot
mode using Nero ShowTime again. After about 30 minutes, it locked up.
First about an 620Hz tone (E-flat) sounded. After a few seconds, about
a 470Hz tone (B-flat) and 390Hz tone (G) joined it. My perfect-pitch
wife identified the tones. The sound came from the PC speaker. I never
use that because I have external speakers. Hyper-threading was not
disabled after reset and reboot this time, so symptoms were a little
different from previously.

You may want to play with how the video is rendered.

For example. look for the word "Showtime" on this page.

http://forums.laptopvideo2go.com/ind...er&f=10&t=7755

They make reference to things like Hardware Overlay (typically you can only
have one of those running at a time on the computer), VMR7, or VMR9. The latter
two are part of Microsoft DirectX. It's possible you have a bug somewhere
in one of those modes, but not some other.

I can't tell you exactly where to look for those. I tried a Nero manual, but
the setting didn't seem to be in Nero. Some programs, when playing video, use
the same CODEC path as Windows Media Player might. And then, it is possible
the overlay setting for video rendering, is actually in some other place
than inside Nero itself. (Like a Windows Media Player preference.)

You can try changing the "Hardware Acceleration" slider for the display, like
turning it all the way down as a test. That might also result in an alternative
rendering plane being used for video.

Perhaps some change like that, will stop the crashing. It sounds like the
program itself is going nuts, or some data structure is overwriting program
code, and the program is jumping off into space. Each Windows OS, has developed
increasingly sophisticated mechanisms to stop that from happening (like NX
or No Execute bit for virtual to physical memory mapping), and those are
ways for the OS to stop something that has "jumped into space".

I tried reducing display Hardware Acceleration. The third level
disables DirectX, Direct3D, cursor, and advanced drawing
accelerations. That allows VLC and WMP to play an AVI file in pivot
mode. I don't know yet whether it will affect the lockup problem.

The Radeon 9000 box says it suports DirectX 8.1 but some program said
it was actually using DirectX 9. I thought that was Belarc Advisor,
but now Belarc Advisor says nothing about DirectX. Is there something
that I can use to report which version of DirectX is actually being
used? Might the version be important to this problem?

Incidentally, I do not have ATI's Crystal Control Center. I have the
ATI driver, ATI Control Panel, and Hydravision (even though I have
only one display, the Dell 2007FP). Windows Control Panel says the
latter two programs were last used on 11/9/2002.

Microsoft DirectX comes with it's own utility, called "dxdiag".

I tried it just now - Start, Run, dxdiag

and a window should open that says DirectX Diagnostic.

On the main "System" tab, mine says:

directX Version: DirectX 9.0c

As far as I know, DirectX can run on top of non-supporting hardware,
and a software routine may "fill in the gaps". For example, I had
an FX5200 video card on a couple systems, which was "almost DX9"
in hardware, but was missing several hardware features. As far as
I know, the machines had DirectX 9 running on them.

When a 3D game runs, it may have more than one rendering path offered
to it. On a system with DirectX 9 installed, the game nay be able to
run a DirectX 8 or DirectX 9 path, and the behavior of the game can
change considerably. For example, it might take more CPU to run the
DirectX 9 path. And some games don't even offer a preference, where
you can switch to the less demanding path.

So while the "dxdiag" utility will report the installed version of
DirectX, it may not report details about it.

http://en.wikipedia.org/wiki/DirectX

"The application programmer had to query the available hardware
capabilities using a complex system of "cap bits" each tied to
a particular hardware feature. For example, a game designed for
and running on Direct3D 9 with a graphics adapter driver designed
for Direct3D 6 would still work, albeit most likely with degraded
functionality."

Finding a program to view "cap bits" for OpenGL, seems to be easier
than for DirectX. Some games that use OpenGL, would even list the
extensions they detected. I don't recollect seeing that for DirectX
games.

HTH,
Paul

Well, possibly updated drivers for the Radeon 9000 would make a
difference, along with the Catalyst Control Panel, which provides
additional controls and information (like which Direct X is in use).
Catalyst Control Panel is yet another kludge that uses the now-
misnamed Microsoft DOT-Net, but once one gets over its DOT-Netness and
sheer size, it does work as advertised.

The Radeon 9000 box says DirectX 8.1, because it was state-of-the-art
at the time. Although the word "art" and anything Microsoft is an
oxymoron, except for Getty Images. Some of those are truly art... Ben

PC Wizard 2005 program says DirectX 9.0c. It also displays poorly in

Any new R9000 driver apparently is part of Catalyst Control Panel.

I have an unused Asus Radeon AH3650 Silent HDMI video board. I
installed it in 2008, hoping it would let me play 720p or higher MKV
files. It didn't help at all, and I was hit by a severse virus attack
about a month later -- days after I had bragged to a friend that I had
never been affected by a virus attack. I recovered from that by a
three year old system backup, so I put in the R9000 for the backup and
it has stayed there ever since. My motherboard has an AGP-4X interface
and the AH3650 has an AGP-8X interface but the two seem to function
okay together. The AH3650 uses Catalyst Control Panel and DirectX 10.
I might try it again instead of a new driver for the R9000.

Russ


The 3650 could be "UVD+".

http://en.wikipedia.org/wiki/UVD

RV635 Radeon HD 3600 Series UVD+

UVD+ support HDCP for higher resolution video streams.
[Of course, whether the card supports HDCP, is another question.
During the "HDCP ready" era, there were issues with that.]

http://en.wikipedia.org/wiki/Compari...ocessing_units

HD 3650 RV635 PRO

Some features on the video cards, are controlled by the bus standard.
The video card driver checks the bus standard, and some features
become disabled, if ATI feels performance would be compromised by
the bus.

I found a tool here, that offers a "UVD status" entry. Try playing
a video on the 3650, and see if the UVD entry here changes at all.
The video player application presumably has to have the software
to access and use the feature.

http://www.techpowerup.com/downloads...ol_v0.9.8.html

That program is supposed to have been written by AMD, but I can't
find it on the AMD site. (My current computer doesn't have an AMD
card in it, so I can't test the program to see what it says. It
would laugh at my Nvidia branded card.)

reboot (as evidenced by the BIOS Setup), and even the first time the
system goes into Windows (as evidenced by Task Manager), but it is
enabled after going into Windows a second time. Hyper-threading is not
only disabled: the line in the BIOS Setup screen does not even appear,
as if the CPU does not have hyper-threading capability, until the
system has gone into Windows once and then restarted a second time.

I discovered part of why CPU hyper-threading gets defeated: When the
computer locks up, the motherboard changes from its normal BIOS (F9)
to its backup BIOS (F6) on reboots until the system has gone into
Windows once. F6 lacks CPU hyper-threading capability, F9 has it. On
subsequent reboots, the motherboard goes back to its normal BIOS (F9).
I don't remember exactly how this dual-BIOS switching works. It's
something for me to investigate.

We have been discussing my computer at home. It uses DirectX 9.0c.
Reducing hardware acceleration allows AVI files to be played with VLC
and WMP in pivot mode. I tried this on my computer at work using its
2007FP monitor in pivot mode. It is a 3.0GHz Dell Optiplex 755, much
faster than my home computer because it has a later dual-core CPU with
faster 800MHz FSB, larger cache memory, dual-channel RAM, Radeon 2400
Pro video using DirectX 9.0c. I don't have VLC or Nero ShowTime on it
but I was able to play an AVI file in pivot mode with WMP. It produced
garbage in the WMP window until I reduced hardware acceleration, but
then the computer was very sluggish and the cursor was very jerky
which is unlike my home computer with reduced hardware acceleration.
I did not run the AVI file very long, so the computer did not lock up.

I ran an AVI file in pivot mode using VLC on my my home computer. It
locked up after about 35 minutes.

Correction to another branch of this tree: The first tone of about
620Hz was produced by the external speakers. The other two tones of
about 470Hz and 390Hz were produced by the PC speaker.

I ran into a slightly suspicious feature of my computer at home: The
Radeon 9000 video board, eSATA controller board, and motherboard USB
controller all use IRQ decimal 16. I have been playing AVI files from
the external eSATA hard drive. My next experiment will be to see
whether it locks up while playing AVI files from an internal IDE
drive, which does not use IRQ 16.

If I run out of other ideas, I will try changing the video board to an
AH3650 next week.

Default Lockup playing AVI file with pivoted display

Russ, what is your need in pivoting your display on this admitted
antique? You have so many variables here...old architecture being one
of them.
