Hi,

I need help: I can play every kind of video files however, in some case, playback is choppy.
The problem appeared since I completely reinstalled my computer.

While the PC run faster for certain tasks, video playing has been disapointing for unexplained reasons.
Unexplained because I installed roughly the same softwares as before and the hardware hasn't changed except for the updates.
-WMV videos of high definition, like 640/480, don't play smoothly
-AVI videos encoded with Asus2 codex (use with Asus graphic card video capture - sort of mpeg2 variant) utter a buzz and freeze one second every 3 or 4 seconds. The videos are recorded properly because once converted to DivX, it's good. I never had this problem before.

Updates include uSP3-beta and various updates listed by MDGx since, DirectX9 and WMV9.

I have FFDshow installed and whether I use it or not doesn't affect the result. Using different video player didn't help.
I didn't try other codex but it's clear that some video settings but everything I tried, any visible setting didn't help.

Of course you enabled a DMA mode for your HDD?

No, I forgot last time I reinstall windows. :oops: (sometimes forgetting happens) Thanks!

DMA fixed the problem with the large avi video files, but not with the wma video. The wma video resolution is 738/520... but my processor is a 1.8 Ghz... I don't know if it's normal that it's still choppy.

Now this DMA stuff exposed a hard disk problem, which is not or less visible when disabled. (See other thread)
