Tivo Freezing...

[outtherealways]

I'm pretty new to tivo. I have a Lifetime sub. and an upgraded hard drive. I also have DirecTV, after awhile of the tivo being on the picture freezes and sometimes it gets choppy and comes back but most of the time it doesn't. I have a series 1 sony svr-2000. If you have any ideas i would love to hear them. Thanks.

How old is the hard drive? Remove the hard drive from the TiVo and test it with the hard drive manufacturer's downloadable drive test utility. If ok reimage the drive, if bad replace it.
