MPEG 1 Problem? No Video

Hi,

I am having problems playing video files. I got video inspector and this other utility and they say it is a MPEG 1 video file ... They say the proper codecs are installed.

These files were playing fine... untill I installed a few more codecs and now all I get is sound and no video.

What else can I do? What did I do wrong?

Help would be appreciated

Thanks!

I was thinking of just uninstalling everything I installed codec-wise and just re-install k-lite codec pack.
