ok so after reading most of the post here..what i've found to work best on MY touch pro is using CORE PLAYER and using total video converter (which can be d/loaded for free here)

and i convert my video files into h264 avi format and i have NEVER had a frame drop yet..that i've noticed and it compresses 300 mb tv showws down to 60-70 mb with out losing quality..ALSO mvk formatted movies will work also as for they too are compressed movie files
