Freeze Tag

Lately, my cable box has been freezing up, which I don't discover until I'm trying to watch a show on my TiVo and it's a still image that's been recorded for an hour. Luckily, a lot of the shows are On Demand or will be repeated, but it's annoying on days like today when I tried to record three episodes of Spectacle: Elvis Costello With... and I didn't get any of them.

On the other hand, I'm not sure Sundance is a channel I'm supposed to get. I don't understand the "tier system."
