Advertisements Our oldest TiVo has been periodically "freezing" on one screen such that it can rewind but will never progress past the freeze point. When it does, using the Live TV button successfully switches to the other tuner, then back again, but it still remains frozen. The only way to "unfreeze" is to change channels, after which it works again -- until it freezes again sometime down the road. So far we've seen no evidence that any recordings have failed and it only happens during live TV. My wife is the primary watcher of this TiVo and seldom watches recorded programming... The TV set was an old one that was exhibiting other issues, so we replaced it. The new one doesn't prevent the issue. I didn't think it would, but I gave it a whirl anyway since that old set was getting more annoying by the day... The box in question is a TiVo HD purchased in late 2007 with an external My DVR Expander drive attached and Product Lifetime Service. I haven't yet run any kickstart codes to see what that might tell me, but I wanted to see if anybody has any specific ideas as to what might be behind this issue or how I might more thoroughly troubleshoot. I'm considering purchasing a replacement drive for the internal and discontinuing use of the external, but I'd like to have a fair idea first if the drive is a likely source of the trouble. So...anybody have any ideas or suggestions for how I can nail this down better?
