Can anyone advise of a fix for audio video lag issues. I am running my 630 PVRs through Control4 system and the audio video doesn’t line up. I used to able to adjust it when I ran my system thru my TV but that is not option the way this system is set up. Do the new 800 have any adjustment options for this? There is also very little information on the audio settings in the PVR menu and Shawdirect said they can’t help if you don’t connect your PVR directly to your TV.
