Samsung DVD-C631P 5-Disc Progressive-Scan DVD Player
Not too bad.. or good
I bought this player a while back, and connected it to my hdtv with no problems, using component cables and progressive scan switch turned on.  It plays every dvd I have tried, and every audio cd also.  It does not play a standard vcd, instead, it plays SVCDs, which are better anyway, since you can vary the effective quality.  I'm pretty sure it will play a DVD-R (Most any player should be able to read this format), but I am sure it won't play DVD+Rs (This is too advanced for most players to play without being designed for it specifically).  It plays mp3 cds, but will not navigate through directories, so you'll have to unsort your music and put them all in the root directory of the cd, and it plays them alphabetically.  This wouldn't have been my first choice if I was going for the best, but at its price, I don't think you can beat the features that it does have.
