Is there a link to the demo.avi file that originally came on the mp4 player, i lost my copy and if i could get a copy of the file, i could use GSpot on it and then figure out its attributes and copy other files in its image

Most China-made MP4 Players use AMV because it avoids any licence issues surrounding AVI or other formats.
It's hard to generalise about the quality of playback of AMV files on the small screen of an MP4 player because there are literally thousands of different models, developers, factories, and firmware versions.
In my view, the quality of video+audio playback only becomes really important above a 2.6 inch screen when it becomes viable to watch anything in more than a postage stamp size.Wholesale Consumer Electronics Direct From China - http://www.chinavasion.com
I had similar issues with creating videos for my MP4 player. Now sadly I don't know how you can identify it, but I though I would provide the transcoding info, so hopefully it would work with your player anyway.
Here is how to transcode a 4:3 aspect source file to the standard 160x128 res for my player:
mencoder -noodml INPUT_VID.avi -of avi -o OUTPUT_VID.avi -ofps 15 -vf-add scale=160:-2,expand=160:128 $3 -srate 44100 -ovc xvid -xvidencopts bitrate=400:max_bframes=0:quant_type=h263 -oac lavc -lavcopts acodec=mp2:abitrate=96
All the best!
From the amv page on wiki, amv can hold a movie in about 80MB.
Most of the above mentioned need to convert to avi or wmv format, then to amv format.
What is best tool or tool chain to directly rip a DVD and transcode to amv ?
Note: These players with this "MP4" name is really bad. The makers claim it only mean "after MP3", the players actually only do amv. But there are many Portable players do really play MP4.
