See previous thread "A-V asynchrony.
I hadn't successfully loaded new firware . That became clear when I became aware of the problems with bass management that were the subject of many posts to the 990 page.
I offer my observations to any further Outlaws having problems with lip-synch (video before audio) using the "old" firmware. I again noticed lip-synch problems after using auto-setup. Reset took care of it. I again used auto-setup and the problem recurred. I reset once more, but didn't use auto-setup. This time I entered by hand the same values that auto-setup had determined for "Channel Calibrate" and "Delay Adjust" and no more lip-synch problem. My conclusion is there's a glitch with the auto-setup program.
Those Outlaws who are sticking with the old firmware may discover more problems. I'm installing the new firmware as soon as my grandson stops playing the XboX.
