Hi Patrick,
How do you have your speakers set up? Are they analog? Set to small or large? Mono sub or Centre Sub or LFE?
Reason I'm asking is that on my 568.1, I have always had an occasional pop from the left or centre speaker on certain music DVD's (concert type not DVD-A's). After a lot of experimentation, I found that it only occurs when the speakers (analog) are set to small with mono sub. It does not happen when any other type setting is applied.
It annoys the hell out of me and I'm at a loss as to what could cause this. To be honest I'm close to giving up on Meridian -- far too buggy!
Regards,
Steve
