Put a DVD or CD in it and works just fine. If you can find it anywhere for the 170.00 dollars I paid for it, jump at the chance. Have tried CD's and MP3's - absolutely no problems and sound reproduction is as good as any CD player I've heard. Explain the technicalities of the options and why one option may be better than another - don't assume that the buyer knows whether compressed is better than uncompressed. Joystick pad on remote is sometimes unresponsive if not totally pointing one direction.
Video looks awesome and sound is great too.
Deffinately your best bang for your buck. Haven't had a chance to play MP3's yet, but hopefully soon. Remote control joystick, mp3 name display, truncated mp3. I have no problem with reading DVDs and scratched VCDs. Audio sounds okay too.
