In the past, when a channel would start breaking up like when you're on a cell phone and you're losing reception.... I would just hit the replay button and it would straighten itself out. Well recently, this is happening too often. Then in the past few days, it has gotten worse on whole new level. Guide comes up blank sometimes, or if you can scroll one page, the next page is blank. There are long delays when changing channels to not even responding sometimes, reboots itself when frozen, etc. Normally in the past, when tivo is done restarting, I know it takes awhile before you can see live tv, but I used to be able to watch the NOW PLAYING list. But now, even that list will be blank for a very long time.
