This one is really weird. At first I thought it was a software upgrade because it seemed to come out of nowhere, then went away for a month or so, and has come back with a vengeance these past few weeks.

Pioneer TiVo with DVD burner works fine for all intents and purposes. Nice and fast navigation. Sits on top of a bureau in the bedroom, under a flat screen.

It will, with no rhyme or reason, crash. I can tell this has happened because the clock freezes. So at 2:36 am, it froze. I see it at 7 am. No buttons do anything. Most freezes have a black image when I switch inputs on the TV to see the TiVo. But if I was watching something, pause it, and then forget about it, the TiVo has crashed while in pause, with the image still up there. But that's rare because I usually finish watching a show, back out to menu, and then switch the TV back to its internal tuner.

The only "solution" is yank the power out of the back of the TiVo, wait a moment and plug it back in. The display goes through the normal sequence, but, for a time, it says something like "no hard drive" but, after a while it finishes booting up and everything works fine. Recorded shows look fine.

I've had to yank the power as many as 3 times in one day, and then it can go several days just fine. Average is about once a day, or every other day. So it _works_ but it crashes and it has missed recording programs because it had crashed and I didn't notice it. I've never had it crash while I was using it. I'd like it to not crash.

I can get a replacement hard drive, no problem, but I'm really unsure about this because I would _expect_ that the clock freezing on a moment in time is not a hard drive issue, or a power supply issue. So I wonder if someone else has experienced this and has advice to offer.
