I've had the MPD820/17 for a few hours now. Out of 10 commercial widescreen DVD's I have tested on it, it refuses to play 7. The other 3 play just fine. This makes me think the firmware needs to be updated, but I have not been able to find any way to do this myself. It will play NONE of the DVD+R disks I have burned myself on a DVD recorder. I will be very happy with this machine if Philips customer support can solve the playback problem, but I am not optimistic.
