Koss DVP2161 Compact DVD with MP3/CD Player
Great value, but with caveats
I've played with one of these for about 6 months now. There is a bit of a heat problem as others have mentioned, I hacked mine to install a small fan (mpja.com part 12929 FN) and have not had problems since. I haven't found any format it won't read, from VCD to SVCD to CVD, DVD-R and -RW, JPEGs and MP3's on a DVD. (80 hours of music on one disk!) Outputs for composite video, S-video, and component video, as well as analog and optical digital audio.  User interface isn't great, but it works. There are buttons for some functions on the player, but Koss didn't include enough to run a typical DVD, you will need the remote (which reduces its portability somewhat).  Video filters are very sharp, which looks really good on some movies but introduces a little edge noise on some others.  Runs on 12vdc, I've used mine in my small trailer with a LCD monitor, it's great to be able to take your movies and songs on the road.
