This has been happening more frequently since I enabled suggestions feature. My TiVo is recording shows on channels that I do not pay for in my cable provider lineup. When I tune to the channel not in my cable lineup the TiVo pops up an alert message stating you must not have this channel in your line up error (v58). If the TiVo tuner could detect there is no signal when trying to record a show it would free up the tuner to record a channel that I do receive. I know, why is the channel listed in your TiVo channels guide if you don't pay for the channel, well I try to keep it cleanup, but with the frequent changes that are made to my cable lineup it would be nice if the TiVo had a feature like this.
