I can tell you the Denon 2200 does not handle dvd-r's well. I have one for DVD-Video and it will typically play 60% of a DVD-R Audio disc and suddenly stop. I've never been able to listen to a complete show with that player.
interesting. my Denon 2200 plays every disc with no problems. I don't have any store bought discs, these are all burned DVD-A discs using Discwelder or DVD-Audiofile.
The one quirk I
have noticed is that it sometimes stops playing after 2 hours of continuous playback. not always, but sometimes. and it'll never stop playback at any other time. all it takes to get it going again is to press stop and then play. and then it continues to play fine, including the stuff after the 2 hour mark. but I've never had a problem with any disc just not playing.
I know that's a weird quirk, and it'd probably bother some people more than it bothers me. That's why I'm not giving it a glowing recommendation, and in a few years, I'll probably get a different deck. Anyway, just thought I'd chime in about the Denon DVD players.
