Advertisements My TiVo HD w/SN 652, SW 9.3a, 2 Motorola ‘S’ cable cards on Verizon FiOS, started picture freezes the last week in June. Originally I could correct the problem with a couple of channel changes or using the review button. After a week I found that I had to do a warm reboot (from the menu) to cure the freeze. The freezes usually occurred following a channel change. I discovered that if I did a warm reboot once a day at my convenience, I wouldn't experience any freezes (or any other problem). I've been doing a warm reboot once a day for a week now. I'm not happy about having to do the reboots, but I am able to use my TiVo without worrying about freezes. I would think that all a warm reboot does is re-initialize the software like the stack, heap, buffers, etc. It appears that the longer TiVo runs after rebooting, the more likely it is to freeze. Perhaps the loss and re-establishment of signal (pulling the RF connector) also causes one of these areas to be reinitialized. Rebooting seems to allow the TiVo to run for at least 24 hours. To maryyugo, I've had two Series I Tivo's since 1999. Both have expansion drives and both have been running continuously. I've had my TiVo HD for a year. Up until the end of June it has been trouble free. My point is that TiVo has an incredible reliability record and hopefully they'll fix this problem soon. Maybe this experience will get them to test future software on employee units for a month or two before uploading it to all applicable TiVo's.
