I found that AMV Converter v4.00 was a complete waste of time for creating video files for the Yepo 757F (1.5" screen). Unfortunately, v3.68 does not convert MP4 video file clips, which are common on the internet:

open-source video

Neither version works that well for the Yepo 757F - about 20% "playable" (high quality setting) success rate on downloaded video clips. The solution is to convert in two stages: (1) use Pocket DivX Encoder (Palm Tungsten setting) to create 128x96 AVI files (2) then, convert these intermediate files using AMV Converter 3.68. The end result is a much higher playable success rate on the Yepo.

See my AMV conversion test results page.

Thanks for your valuable input into this.
I will put this as a sticky.
