As for the real classic TV networks, from looking at their schedule I'd consider Me TV the best, even though I only get to see it on weekend late nights for the most part, thanks to the sorry treatment they get from WBBJ in Jackson, TN. I'm hoping that Me TV will either force WBBJ to go to a full subchannel or move to WJKT in Jackson.
Antenna TV is really the only channel I can get all the time since they come in on Charter Cable from WREG in Memphis. I'd consider them the next best, although most of what I like is on Sundays (Barney Miller and WKRP) or late night (Alfred Hitchcock, Burns and Allen, and Jack Benny). Once they change their schedule after the first of the year to where there are 2 hour blocks of Barney Miller and WKRP during the week I'll probably watch them more, although I wonder what they're going to on Sunday nights. I agree with another post (possibly in another thread) that they need to cut back on the Norman Lear shows on weeknights. Sanford and Son is the only one I'd want to keep.
I only got to see RTV on trips to IL during the time they were more like Me TV and liked it at that time, but they have become probably the worst classic TV network now. I don't know if anyone near me even carries it now.
I don't know if I'll get to see Cozi TV any time soon, but from what I've read about it here, they sound like they might be better than RTV, but not as good as Me TV or Antenna TV.
