I have noticed the lag on the screen guides and channel up and down on the VIP DVRS. I install these daily and there is a noticeable lag on them. I seem to have found a way to fix the tv1 lag by making tv1 UHF, and you can also change the tv2 to either Band A or Band B for the best performance.
Have we noticed? don't get me started on these slow ass menus on my 722K. LOL.
Wednesday my menus were so mind numbingly slow I almost threw my remote through my television set.
Thursday, it was like nothing was ever wrong in the first place.
This bug, drives me insane. My brother and dad with the same box and software version, never see this problem.
Arrrggghhhh!!!!
I have gotten to the point I will try anything, but no fix seems to last more than a day at the most.
If L681 does not fix this I may be forced to try another reciever.
