Hi, I have this problem, after I reinstalled my WinXP SP3. My VLC player plays *.avi very jerky and choppy. CPU shoots up to 100%. However when i use the WMP9 to play the same avi, WMP9 works. 1. I reinstalled WinXP SP3. All drivers are in and working. Installed codec packs, DirectX and etc. 2. I installed VLC 1.1.11(latest). Plays avi(s) but very very choppily and jerky. Tried DMA, buffer 5000msec. Did not work. CPU is 100% and system slows down. 3. WMP9 plays avi(s) fine. 4. This was working before the crash. Not sure what is the problem. Anyone can help?
