I went to watch an episode of Law & Order and it only got the last 17 minutes of the program. The TiVo also reset itself the other day when mom says it did when she pushed too many buttons at once. I suspect a failing hard drive but I want to know what the exact symptoms of a failing DVR/TiVo hard drive are.
If it is failing, I'll probably just get a Comcast DVR or get the whole-house DVR offering from Comcast. I might replace the HDD in my TiVo at a later date when I have spare time. I am not in a position to replace the TiVo because I forked over a boatload of money for the box and lifetime subscription. I might look into the X1 DVR as well. I have a Comcast DVR in my bedroom and I might move that downstairs since I rarely watch recorded shows in the bedroom but the living room gets plenty of DVR usage.
You should go here and ask about your problems. It is a tivo help forum.
