6800 Ultra DVD playback observation
I've not seen smooth DVD playback with any nvidia driver later than 61.77 on
my 6800 ultra. Anyone else noticed this? It's slightly choppy, only slightly, but noticeable enough to spoil the viewing experience. 3.2 GHz Prescott, 1GB RAM, running Driver Cleaner 3 every time I change. Games work fine with the later drivers though, but I'll be sticking with 61.77. Could this be related to the buggy non-functional video processor not providing motion compensation? Perhaps this is why the other drivers are still BETA? Would be interesting to know whether it's just my system. LK |

With respect to your question "Could this be related to the buggy non-functional video processor not providing motion compensation?" I would say no, it couldn't. Firstly the video processor does work - just not with HD WMV's, and secondly any choppyness with HD WMV's is caused by the CPU usage being too high. (6800's play HD DVD's perfectly smoothly if you can keep the CPU utlization away from the 100% mark.) Yet with your DVD playback CPU usage is probably only 10% or less anyway. Chip |

. .. I've not seen smooth DVD playback with any nvidia driver later than 61.77 on my 6800 ultra. Anyone else noticed this? It's slightly choppy, only Upgrade your drivers . . . What I was trying to explain was that I *did* upgrade the drivers and found they didn't work 100% properly for DVD playback. So I went back to 61.77, the current official nvidia driver, which does (on my system). The DVD decoding software is up to date (Power DVD). Also, one other thing I didn't mention is that WMP will not play DVDs at all well using this decoder with drivers later than 61.77 - it stutters like hell. Power DVD itself is much better but not smooth. But everything works fine with 61.77 - strange. LK. |

LK,
You have a problem, my 2.8Gig Northwood using a 6800 plain plays back HDTV wmv's like "Step Into Liquid" absolutely perfectly with 49% utilisation on one h thread, 0% on other. 70.41 drivers. Cheers.

Cheers. Pete Pete, ALL 6800's currently out in the market have the HD WMV decoding problem. That includes yours. The symptoms you see are perfectly normal for a P4 with HT. It doesn't mean your decoder is working: It isn't. Chip |

Chip No thats not what I said, he should still be able to play wmv clips alright with a P4 and a 6800Ultra without the decoder working. |
