I think the audio lag problem has gone away. After disconnecting the 990 for a day while I used my old Yamaha I reconnected the 990. I've tested with a few DVDs and I don't hear the lag in audio like I did before. Did leaving it unpluged from power for 24 hours fix it? I didn't make any other changes. It was not my imagination. Well even if it was I'm happy now and I won't be sending it back.

that's interesting.. i may give that a try as well. Did you lose all your settings when you unplugged it for a day?

No I didn't loose the settings but I did a reset it a couple days before and that does wipe out the settings. If you haven't reset the unit I would do that too. The directions to reset are in the back of the manual.

I will try a hard reset tonight.. i have played around several times when the lip sync delay. and i can't seem to get it right. the audio is always off slightly. so a reset is on the menu for tonight.
