Okay, whether I use xvid, divx, klite or any other codec...I get the same results.

I also ran Gspot and it says I have all the neccessary codecs for audio and video.
This is one of the more frustrating things I've seen related to my cab. Again, if the vids never played correctly, I'd know my configuration was wrong. But since they do play sometimes (about 1 out of 10 times), I'm stumped.
It has to be something so minor, but I just can't pin point it.
Any other help is most appreciated!
