Hi. Hope I'm posting in the right place..

Anyhow, using the mce 2005 xp upgrade. Installed rollup 2 update. Ran mce for the first time, and videos weren't working. The audio plays, but that's about it. Installed the Nvidia pure video decoder, and now when i start playing a video, it jumps straight to "playback stopped". Same thing with DVD's. Plays fine outside mce. I've reinstalled 3 times already, but it does the same thing. Checked all my drivers, and checked hardware for compatibility. Any help would be very much appreciated.. Thanx in advance. (btw, I didn't install any updates the third time)

Specs:

Intel 3.0Ghz, 512MB RAM, Geforce FX 5800 128MB, 80BG WD, Onboard Audio, Leadtek PVR ( Not installed at the moment )
