playing video- dx9c issue

[chexmixbbq]

ok, i coppied this from another forum, but i have the same exact issue as this guy, and our specs
are pretty much the same. if anybody could find out how to fix this, that'd be great.
i've spent days searching online for a solution, nothing seems to work.

here's the problem-


I'm running a WindowsXP sp2 System
AMD athlon 2000Mhz proccesor
1,5GB ram
256mb GeForce 6600LE (nVidia)
and so on...

Ok at first everything seems perfect, I can play (new) games, do Photoshop and illustrator I can edit in AfterEffects and Flash blablabla...
BUT I CAN'T PLAY ANY VIDEO FORMAT!!! (exept flash video)
Everytime I try to play a video (all codecs are at the system) my system jamms like a rock.. it looks like I have a framerate of 1fps or something. Only when I open the task manager my CPU drops back to 0 (instead of 100%)
and I can close the app.

Ok, it's not the memory (tested that)
it's not the mediaplayer (tried all at the market)
it's not the codec's (tried all formats)
graphicscard seems fine according to the DXDIAG wich says that everything is alright. The Nvidia helpdesk couldn't figure it out either.
I've been on a lot of help site's and I'd tried every trick in the book but nothing seems to help. :@

It all worked once until I decided to buy an extra harddrive and re-install Windows.

The only sign I had of what it could be was when I tried to play an divX avi in divX player, it said that I have to re-install my directX, wich I've done tons of times just like re-installing my graphicscard.

pleeeease somebody tell me how to fix this; its annoying the hell out of me and wasting
lots of my time. i have sp2, dx9c, latest nvidea driver, k-lite codec. tried playing my movies
with lots of different players- wmp11, wmpc,- each end up with the same result. i don't want
to uninstall direct x, fearing it will lead to other issues.

thx for reading, plz help me out

I know you don't want to hear this, but when all else fails, you should back up everything you care about on your OS partition, delete the partition, and reinstall Windows XP and SP2. (Place a recovery point at this time. Then start slowly adding the drivers for your stuff. (Run the video player each time so you can see if it is something you have added to the system. ) I know this is a bit monotonous, but it might just lead to the actual problem. (Before removing the partition, you might also try running in safe mode and see if the video is any faster)

Try playing them in VLC - it doesn't use codecs.
