Advertisements I'm having periodic issues where shows fail to record because of either "no signal" or "not authorized" issues. It only happens on one channel; I've yet to find a failed recording on any other channel. I have Cox for cable and plan on talking to them but from looking through the message boards I've yet to read of anyone with a similar issue ever having it permanently fixed. The work-around always seems to be regular rebooting of the tuning adapter. One of the biggest annoyances of this problem is that by the time it is known several recordings have been missed. (My problem channel is the Tennis Channel; when there is stuff to record there is often a lot of it.) I've been exploring the telnet interface and see that I can change channels and tell the tivo (a Roamio) to record. Assuming this issue is never properly resolved (and how would one know it was never going to happen again?) I've pondered some code that telnet to the tivo, change to the tennis channel, and if see if it was recording. If not, the script would tel the tivo to record that channel, then check that this is actually happening. Where I'm stuck is in trying to set up a short, manually-timed recording. That is, change to channel 1315 and then record for 10 minutes. Not record an entire show. (My concern is in accidentally crating a recording conflict.) Is there a way to do this via telnet? Also, is there someway via telnet to tell if a channel is coming up as "no signal" or "not authorized"? I've been searching but found nothing to suggest this was possible, hence the test recording approach.
