Hello. I'm new to all this and not exactly sure where to post this question. I have a recently installed home theater with the Marantz S2 DLP projector, Interga 8.3 AV receiver and Integra 8.3 DVD. I'm thrilled with the room, except for lip sync issues I have on most (but not all) DVDs. The audio usually lags behind the video by quite a bit. The Integra receiver allows me to adjust the AV sync to a delay of as much as .74ms and this often helps. But I don't want to have to adjust a different delay each time I put in a different DVD. The DVD was connected direct to the projector until yesterday. We changed that to run it through the receiver, thinking the video was just reaching the projector faster than the audio to the speakers. It helped but not a whole lot. Is this a common problem with this set up? I haven't seen much on the threads about it. I'm not even sure if the problem is with the DVD player, the receiver or the projector. Please put me in the right direction. Thank you!
