PhilipPeake said "The real answer is to tag sound and video with sequence numbers to allow the pair to be matched up at some point - ideally in the receiver, but this would add to the expense of the receiver. Simply doing this at each (re) transmission point would help a lot."
I agree with Mr. Peake that his suggestion is the real answer to the problem, and computer gurus may be working on that solution now. Updating a standard, however, is typically a long process, and implementing it can be even longer.
A couple of weeks ago I sent Dish Quality an e-mail regarding the lip sync issue, and received a very polite response (which I appreciated). Their comment in response was, in essence, that they're working feverishly on the problem but there are just so many weak links in the chain that its tough pulling (i.e., they keep finding different causes in different situations).
For the interim, I would be satisfied with a 722 update that would let me manually set the audio delay. If I'm watching a program that will be 3 to 4 hours in length, I wouldn't mind taking 15 to 20 seconds to set the delay. This would be especially easy if Dish provided a guide with recommended settings depending on the type of material being viewed, and could be done as an upgrade to the current lip sync feature (I would hope). I think I'll e-mail that idea to Dish.
