I've recently bought an AV300 and DV79 based system and overall I'm very impressed with the performance. However, there seem to be 2 problems (reproduced on my suppliers demo system too, so it looks like a software issue): 1. If you use the RC codes in the back of the book to programme a remote (in this case a Marantz 5400), the code for Zone 2 simply switches the AV300 to the PVR input - wrong code or software error? 2. I have the Maroon 5 Songs About Jane enhanced CD and it comes up as a "bad disk" on the DV79. Taste aside, I think this reflects a further software issue (same problem shown in the shop, where other DVD players from Denon etc. had no problem). Anyone else seen these problems and is there a fix on the way?
