I totally agree as to the usefulness of this feature. ComCast's given  
us some trouble in the past, concerning cable functionality. Both  
times, they've had to end up cutting the main cable feed to the  
house, and in both cases, it interrupted a recording. When the cable  
feed was restored, I had my recording, but for some reason, my  
PVR-150 just gave me a corrupted recording (as in Myth would freeze,  
and I'd have to skip around the problem, until it happened again).  
I'd have loved to see Myth record only the parts where the cable was  
active, and give me two (or three, or four, or whatever) recordings,  
instead of one horribly awful recording requiring constant adjustment.
