Why is tcm on xfinity in both sd and hd option on demand coming in with a block box around the picture?! In 2016 this happened- and turned out tcm had been sending to comcast a error- hd format for sd option. I think its same issue- Ive sent messages to tcm online to no avail. Anyone else notice this? What else to do?! Hard to watch some movies size of a stamp. UPDATE-TCM replied via my message to them via facebook, they say they are forwarding this issue to their team and to also alert comcast as well. Idk if they will really fwd the issue or not but that what the message states.
