Sorry for bringing up this issue once again ... My question now is: When watching TV and having the TV's sound being processed to let's say Pro Logic II and amplified by an up-to-date AV-receiver, will it then be inevitable to experience noticable lip sync delay in any case??? I discussed that issue before: http://www.audioholics.com/forums/showthread.php?t=6763 I am pretty uncertain at this point whether I should return my model to the retailer or not. That would only be a waste of time if what I found wrong with my model would be the same basically with any other AV-receiver available. On the other hand, if not all receivers "feature" this lip sync problem but only those by YAMAHA, it would make no sense for me either to have my model exchanged for another one by YAMAHA ... :mad: So, how should I decide? Thanks a lot!
