I just got a Toshiba 4960 today - and I am returning it tomorrow.

3 problems right off the bat
gaps with dvd-a discs burned in wavelab
composite video out does not work
play/pause and stop buttons on remote do not work when a disc is in the player (sounds crazy but true)
I tested a Pioneer 578a at Curcuit City today and it seemed to work fine - no gaps at least. I think I'm gonna pick it up tomorrow
