In my plasma TV set-up, I experience some sound/picture sync problems due to the plasma's picture processing, which can delay the picture somewhat. Sound can be a little ahead of the picture. I know that there are some Receivers and preamp/processors out there that allow you to dial delay into the sound output, to help match sound and picture. Does anyone know which brands or models can do this? I know the new Anthem AVM20 can do it, but it's pretty expensive. I'm hoping for a receiver, but will consider separates if necessary. Thanks for any help. Rich.
