I've got a JVC XV-523, and I'm very pleased with the audio and video quality. It doesn't have very good disc compatibility, though. I recently bought a DVD-A disc, and while it plays it most of the time, it will occasionally skip even though the DVD player is on a level surface. It doesn't do this with any of my DVD video discs.

Is there anyway a firmware upgrade can fix this problem? If so, does anyone know where I can get one?

Thanks...
