there was a thread about this awhile back - I'll see if I can find it
I believe the issue with the 4960 was a buffer issue - I have tried the Wavelab dvd-a's in several players (even a JVC that said it would play dvd-a, but not dvd-r, but it did - flawlessly) - I'm guessing it is the player but what the hell do I know???
I am all for budget players, but...
imo the 4960 is a pos (not that my Pioneer is much better - it is not - but it plays my dvd-a's so I'm happy)
