Advertisements I agree that it must retune the channel for the next recording. I have witnessed it live going from a "missing channel" to fixed just by retuning the same channel when it went to record a show at the tope of the hour. See Item (d) under "What Happened" http://www.tivocommunity.com/tivo-vb/showthread.php?p=4883540#post4883540 However, I believe that there are two different "flavors" of the missing channel problem -- one in which a "retune" or channel change would fix it and one which required a reboot. I had one whole evening of prime time shows on one channel end up as zero length recordings when I had the second flavor. Other shows recorded on the other tuner recorded just fine. Luckily, I've had ZERO missing channels/partial recordings since 8.1 rolled out (knock on wood). All my observations above are pre-8.1.
