I actually picked this up on Amazon a week ago and got it in Wednesday. I couldn't be more pleased with the thing - it plays all DivX formats (3,4,5), XVid, MPEG4, MP3 - really, you name it, it plays it.
One lesser known feature is that it has a data CD/DVD browser menu system built in, so not only can you listen to your MP3s, but you can sort them and browse them on your TV by album. Same with your JPEGs.
This player is really top notch, and at the price it's a steal.
