Thanks to everyone who tried to help!
I finally solved the problem by accident.

I got so mad at the choppy audio, installing and uninstalling codecs and converters.
It had nothing to do with the converter or codecs or the MP3 Utilities. It was the darn firmware!!!

Well I upgraded to V3.5.37 (of course after I backed up my current firmware)

My player on the setup screen identified itself as a sc85051c board. I used the MP3 Player utilities 4.0 to u/l to it, after I d/l the Italian firmware file. I then changed it to english and I was amazed. It didn't even erase the files I had on the player. Seamless transition and this firmware makes my player look a whole lot better! The AMV files that were choppy and slow are fast and perfect.
