Another channel they could do that with would be FXM (Fox Movies), which appears to only be available in SD on Directv. I like older movies and at least TCMHD is upscaled so it looks halfway decent on a large screen TV (although many of their film transfers were done prior to HD).
Just curious, oftentimes when I see historic episodes of game shows from the 50s-90s on Youtube, it says GSN in the corner. I haven't seen anything like that on the GSN channel we get. Is this a different GSN channel we don't get, or does GSN occasionally show older things too?
I recently came over from TWC, and the only other thing I can think of that I wish they had here was part of the EPIX lineup, called "Epix Drive-In." Lots of cheesy goodness, as the name implies.
