I'm on a 2.2ghz Barton, 1gb of memory, and a 6800Ultra w/ the latest 71.84 WHQL drivers. I am using WMP10. CPU load is always less than 75%.
Could it be a codec problem?
under windows media player options, performance tab, advanced button, select keep "drop frames to keep AV in sync", if it isn't checked already. windows media player options go for every player using the windows media control which is quite a bit. i have no clue why your cpu is at less than 75%, very odd. there must be a bandwidth problem somewhere. memory? what codec is causing this problem? it's probably not a problem with the codec if it only happens on your machine though. also make sure windows media isn't delegating decoding to the purevideo chip on your card (to help diagnose). if it is, it could be a driver issue. i've had this exact same problem with Media Player Classic but i haven't tried toggling the 'use WM ASF seeker option'.
Update: i think the video the OP posted is screwed up or something. i seem to have the same problem no matter what player i use. the windows media HD videos in the microsoft HD showcase have no problem.
Cool, lots of good advice!
I have "drop frames to keep av in sync" already checked off. My memory is Pc3200 running at 200mhz FSB @ 2-2-2-5 timings. How do I make sure its not using the purevideo chip? Isn't it supposed to help anyway?
Anyway, I see your edit, do you get the same problems I do?
EDIT: Thanks for helping!
yeah that video is f'd over, if that's what you're referring to. the guy's voice goes down to half frequency and sounds like an alien. then the video stutters all over the place. i don't have this problem with any other wmv hd i view. does the problem happen with every WMV HD that you view?
yeah, purevideo is
SUPPOSED<- to help, but there might be a problem with the drivers causing the chip to return corrupted video/audio data. that's the only possible explanation i can come up with. however since microsoft hasn't even released the patch for wmp10 that's not possible at the moment. i think more than a patch is needed for this, nvidia doesn't even have their wmp10 directshow filter out (maybe nvidia delegates that part to microsoft). that's still a possible problem for MPEG2 videos though. if nothing else it's probably some weird, malfunctioning codec that got injected into your system.
by the way, i use memory with the exact same specifications. also i have the 6800nu and using 71.84 drivers. looks pretty identical except for processor (i use athlon64). but the cpu's not an issue if it's not even being pushed to its max. my cpu hovers around 25% usage while playing that video and i get that same problem. but like i said that's the only video i've encountered a problem with.
as to how to disable purevideo, uhhh...the only option may be to install drivers earlier than 67.66 (i think that's the version), to make sure the feature is completely, temporarily rid from your system. anyway i
SERIOUSLY doubt that's the problem since your card (in AGP) doesnt feature the wmv acceleration. since you list an athlon xp processor i assume you're using agp8x.
so anyway.... here's what you should do at this point:
try another video, and if it doesn't work, post back and i'll try and think some more about the problem...i'm confident that will fix it.

download any of these videos and see if you notice the effects you first described.
if anyone has a question about directshow/video playing i can answer it because i've programmed and messed around with directshow for at least 2 years.
