I have experienced the same drop-outs of signal. It doesn't happen on any other cable channels. It's really a pain. I sit to watch and the picture will blip to black and freeze and the sound drops out.
I have Mediacom cable and they checked it out and said the problem must be with TCM. It's really a pain. IS this some method TCM is using to keep people from recording their channel? I don't record but I sure hate being distracted by the falling signals.
TCM, please look into this and let us know why your channel poses such a problem for us subscribers on your channel. Fox is starting to run old movies and I've been over there more as never any signal issues ever.
Please Fix
