Hopefully, someone can give me some insight. I bought a Tivo HD last week to replace my perfect Tivo 2 and have had all the problems talked about in the forums treads. Cable guy installed the SA cards on Friday........ No video, grey video. Loss of huge groups of channels and lockups. I've rebooted a hundred times and reset the SA cards as many. I'm ready to box it up and ship it back to Amazon. Then drive back to Cablevision and get thier clucky DVR I've used since last year with no issues. Can someone assist/convince me not to ship it back to Amazon! Any help would be appreciated!
