This is a strange problem that I have never seen on a tivo before.

I have a series 2 (old style with dark Grey front) tivo that I put a new 500 gig hard drive in. It worked fine and good for about 2 months. But then I noticed the first problem.

1. It would not keep up with the tv. It would be back to 30 min behind. If I didnt use it for awhile I would have to fast forward it to real time.

That problem seemed to fix itself. But now for awhile it would lock up during live tv. It would lock up and then skip a few seconds to catch up to the live feed. It would only be a second or two. And when I play back a recorded show it would not show the skip. It would just have a weird cut where you could tell a few words of a characters sentence was chopped in half.

I thought maybe because the direct tv was HD on that tv I changed it to a regular Direct tv receiver and it seems to still do it.
