Convert .mov files to .amv and playing amv files in mp3/mp4
 

I got an MP4 Multimedia Player and I have two problems :
1. It came with the AMV Convert program and Player in a CD I can convert some files to amv extension and play them in the computer with no problem but when I put them in the MP3 player it only show some lines as image and I get the audio ok. What can I do??
2. The AMV Convert program says that to convert .mov(quicktime player) files I need to install the DirectShow filter, but I can not find that filter anywhere, Anyone can help me please???? Or someone know about other way to convert .mov files to amv??
