I came back from a trip to find that some older programmes I'd not yet watched had been removed to make room for new recordings. Bit of a shock that was, as I've never had that happen before even with lots of programmes.
I've a 120GB disc in the TiVo, and the System Information is reporting only 37 hours at best quality. Does that sound right? I'm sure that I've had more than that on there in the past.
