I have FiOS i the Northern VA area with 4 tivo HD and one of their moto dvr's. All 4 tivos pixelate, the motorola DVR does not. Swapping cables between the moto and the Tivo yields the same results, moto is just fine, tivo pixelates. Do not have 9.1 yet, just signed up for the priority list, we'll see what happens. However, at least for me, the problem is bad enough to where any HD show I record off the fios channels are pretty much unwatchable as pixelation occurs every 2-3 seconds. The odd part is a reboot fixes the issue for about 24 hours, but obviously thats not a solution. Got my fingers crossed that 9.1 fixes the issue, though all the 9.1 bug threads make me wish I had only signed up one tivo for the priority update.
