Lefty11,

The issue with Coreplayer isn't with mp4 files in particular, it's with h.264 encoded video. You can encode an xvid inside an mp4 wrapper.

I bet your video that file you say is playing well in coreplayer either isn't h.264 or isn't 640x480 in the 700kbps range.

H.264 video at 640x480 at 700kbps won't play acceptably on a TP using coreplayer.

There are some good wikipedia entries to learn about the options with wrappers and codecs.
