Default What is "Built-in AI Auto Speed Adjustment" in Asus DVD-ROM drive + can it hamper performance?!!..

p wrote in message ...
Hi,

I was wondering if the "Built-in AI Auto Speed Adjustment" feature of
DVD-ROM drives like the "Asus DVD-ROM drive 16x/48x" can hamper the
playback of avi files from cdrom (esp. those encoded with DivX which has
higher requirements I believe). What I mean, won't you get some latency
every time you start playing a DivX avi file from cdrom cause the drive
will always calculate the needed speed first, so couldn't this give
latency everytime you start playing an avi file from cdrom?

And what about installed games that only need to access the drive from
time to time, but every time the drive will be accessed the Built-in AI
Auto Speed Adjustment feature will always first re-initiate calculating
the needed speed again which could give latency, isn't that so?

PS: anybody who has the "Asus DVD-ROM drive 16x/48x" by any chance and
can tell from experience?!!..

Thanks in advance for all good feedback!

Mike.


I have a lite on that has a similiar technology. You won't notice a
difference. When I play Divx movies, I cache 64M of data so I never
fall behind. Theoretically, it will slow down and speed up depending
on the quality of the disc (pressed vs burned) but in reality, there
is not that much difference between 48x and 32x. You can rip the CD
in like 2.5 minutes or 4 minutes but it still takes 10 minutes to
install the damn game.

Probably the same deal as the Lite-On SMART-X feature. The drive does not
wait to figure out the correct read speed before it can start reading data,
it just starts reading data and adjusts the disc speed based on how fast the
software is reading.
