Hey guys i've been using my new TiVo for about 3 weeks now and i have it hooked up to my NTL Digital STB and it was all working fine until xmas when i started getting a problem. After around 2 hours of the Tivo being turned on the picture to the TV will just cut out. you can still control the Tivo as i can change the channel on my STB with Tivo and can go into TiVo menus but i just can't see anything. When I press AUX on the remote i see the STB picture so its still going to the Tivo. The only way i found to get it back normal is to unplug the Tivo at the mains and leave off for an hour then it's back to normal on power up but only lasts another few hours until the picture disappears agen. Any suggestions what i could to or what it could be as it is now making me relluctant to use it due to consantly hard reseting it.
