WMV 720 HD videos choppy?

I have an Athlon XP 2500+ Oc'd to 3200 speeds, a 6600GT 128mb AGP 8x, 1gig of PC-3200 ram

And yet 720p HD videos are choppy. What can I do?

Maybe your hard drive transfer rate sucks, or the videos are really fragmented on there.

1. Defrag
2. Remove all spyware
3. Use lightweight video player
4. Close all non-essential tasks
5. Profit.

make sure its not the source video too ...try different files from different places.

1. Already Done
2. Spybot, and Ad-Aware detect none
3. I have tried using VLC and WMP11 same results
4. Thats like the first thing I did -_-

I have a WD 80gig 7,200 RPM, so no problems there.

Oh the videos were downloaded using uTorrent off of http://www.mariposahd.tv/

Upgrade processor. It might be fast but it doesn't have multimedia instruction sets used in modern processors which might result in extremely bad performance on certain tasks.

As for serious advice, do you have a recent video card driver? Are you watching the video in overlay mode which is accelerated by graphics card or not? I have same graphics card as you and a 2ghz processor, the video from that site in 720p runs perfect in media player classic using ffdshow with postprocessing enabled. You can try to disable postprocessing aswell.

Err actually nevermind, I need to clear my head. it used WMV9 codec instead, no form of post-processing enabled on it

I use a 2800+ running @ 2.5GHz w/ Radeon 9600 @ 400/500 and have no similiar problems.

720p in Quicktime runs fine here on my 2.53 GHz Celeron at work with 1 GB of RAM.

1080p manages 16-20 fps.
