DIVX and XVID playback problems

[cjanim03]

I seem to be having a problem with my computer playing both DIVX and XVID videos . I have been using bsplayer v. 1.00 RC1 to playback my videos on my computer (but the problems still persists, even worse with windows media player). The problem is that when I start a video, the sound and the video both either 1) play slower than normal speed (sound/vid stuttering), 2) start playing slowly then the video will freeze, the audio will play as it should, then the video will jump to where the audio is and then they both will slow down again, or 3) they will play slower during more complex scenes in the video.
The videos I am currently trying to play are encoded using (According to GSpot Codec Information): DivX3 Low-Motion (4CC: div3) and DivX 5.0 (4CC: DX50/DIVX).
Now I have tried just about every codec I know of, alone and with combinations of codecs: 3ivx D4 4.0.4, Divx 5.0.5, DivX 5.1.1, DivX 3.1.1 alpha, DivX G400.2 83, FFDshow 20030523, FFDshow 20020617, KLCodec 203F, Koepi Xvid 1.0.1 05062004, Koepi XviD Dec 1.0 Beta3, Xvid 1.0 09052004, and Xvid Root 240220031100. I even used Codec Sniper to delete broken codecs. I also tried to fix it by turning my Hardware acceleration down a notch (still no difference).
My computer is weekly scanned for viruses (virus scanner updates everytime I connect to the internet), hard drive is optimized with Speed Disk, junk files are deleted, and spyware/adware is erased and blocked.
I am running my computer with performance settings set to:
Processor scheduling: Background services, Memory Usage: Programs, and Virtual memory: Custom size: 2000MB - 3000MB.
I usually don't have anything else running while my video is playing, nothing even in the background. My HD size is 37.2GB with (currently) 5.34GB free.
Now a long time ago, I didn't have any problems with playing video files, but now I do. There was one thing I did that seemed to work better than anything else (but still had some jitter in the sound & video at times), using mplay32.exe in the System32 folder (the really really old windows media player).

If you have any comments, suggestions, or know of anything else I can do, codecs I can use, or anything I should try with my computer, please let me know. All my computer information is listed below. Thanks.

EDIT : I have solved my problem! If you notice symptoms like cjanim03, it means probably that your CPU is too hot! Mine was at 88°C so I have cleaned my fans and all seems fine now..

I have the same symptoms as you...

And my computer is newly formatted!!

I watch 4-5 divx per day and never got playback problems.. But the fact is that I don't often reboot my computer and when I had to do it, the playback of my videos became problematic.. Since I wasn't able to remember what I have installed or what would be the problem, I decided to simply reformat my computer.

This didn't solved my choppy playback problem (as described by cjanim03)

Please help me if you can. All that is installed for now, are the latest video and audio drivers, divx 5.05, xvid, ogg, windows media codecs 9, and realmedia codecs (for .mkv), morgan stream switcher and direct vobsub.

I use the media player classic 6.4 for playback..

Don't tell me the problem is slow cpu or slow memory, since I used to be able to play the same avi files fine (before the fatal reboot)

I have set my videocard direct 3d and OpenGL to Performance instead of Quality (ATI All-In-Wonder Radeon) and this didn't solved the problem.

ANY Help would be appreciated!!!

TIA,
