Philips DVP642 DivX-Certified Progressive-Scan DVD Player
Excellent, especially for the price
I find this DVD player almost unbelievable for the price.  As others have mentioned, it seems to play many multi-media file formats as well as doing a reasonably perfect job of playing standard DVD disks.  With so many reviews already, I mainly wanted to cast my vote (I noticed I haven't given 5 stars to anything yet).  Here are some additional details to add to all the nice info supplied by others:  1) To try to push its limits, I inserted a backup DVD disk containing 4GB of files from my work computer.  Deep in the disk, I had some jpeg files.  I was able to navigate to these without problem and play them.  2)  Pictures come up pretty quick too.  Not as fast as on a new PC, but very acceptable speed.  3)  One click of the right arrow button rotates them 90 degrees - also pretty quickly.  4) The zoom function is good too.  And unlike a different brand DVD player I tried, the Philips 642 stays in the zoom mode even after moving on to a different picture (as it should :-).  5) Zoomed in images look good (assuming the original is high-res).  In summary: for the price, I would definitely recommend buying it!  Please read the other reviews for more comments on features, playable file formats, etc.
