Martin O'Donnell pointed out this Tech Bargains article reporting that the Philips DVP642 DVD/CD/MP3/DivX Player is in stock at Amazon.com. Tech Bargains calls the DVP642:

... currently the hacker's favorite DVD player. Plays downloaded movies. DVD, DVD-R/RW, DVD+R/+RW, CD, CD-R/RW, VCD, SVCD, MP3-CD, MPEG-4, Picture-CD and DivX 3.11/4.x/5.x, AVI.

... as well as about 7 or 8 other useful formats. The best part is that you can burn files in any of these formats on to a DVD disk and the DVP642 player will figure out how to play them.

The Philips DVP642 is number on on the Amazon.com Electronics Top Sellers List, so it may not be in stock for long.
