Philips DVP642 DivX-Certified Progressive-Scan DVD Player
MPEG playback quality leaves something to be desired
The key frames are not handled well by this unit when playing MPEG4 DVD's, so the picture tends to cycle from excellent to fair every five to ten seconds.  I don't seem to have this problem when playing back under Windows Media Player 9.  Also file titles are truncated at 9 characters or so when displayed, so if your files all start with similar names you will have problems picking them out.  Other than that I am impressed with the wide variety of formats it plays.
