Magnavox MPD820 8-Inch Portable DVD Player
DVD+R
I don't see in the specs that it will play DVD+R and DVD+RW.  Happily it plays the DVD+R's that I have burned.   I did find that the volume on my DVD's was a bit low, but Radio Shack had a good small amplifier to plug into the phone outlet and earphones with adjustable volume which solved the problem.  Regarding JPEG's, it does indeed display them from a CD and automatically start a slideshow if there are multiple photos.  I am very impressed.
