I setup a manual recording SP to record one channel 24 hours, every day.
It is probably not a big deal for a Tivo HD since it is doing it anyways, but this is probably going to prevent the unit to reboot itself (at least intentionally)
I don't expect frequent software updates on a HD XL, so this is probably not a big deal. I have been doing this for about a month now.
Anyone done this for a long time? Any problems?
