I have Charter Cable in the Atlanta area. This is our lineup:
WSBHD - Local ABC Affiliate
WGCLD - Local CBS Affiliate
WAGAD - Local Fox Affiliate
WXIAD - Local NBC Affiliate
WPCH - Peach TV Digital (Rarely an HD Broadcast)
WPBAD - PBS (Rarely an HD Braodcast)
WUPAH - UPN (Rarely an HD Broadcast)
ESPND - ESPN HD
ES2HD - ESPN2 HD
FSNSH - Fox Sports South - Always Off-Air
VSGLF - Golf Channel
HDT - Dicsovery Channel
TNTHD - TNT
UHD - Universal HD
MHD - MTV HD
A&EHD - A&E HD
HISTD - History Channel
HDNet - HDNetwork
HDNMV - HDNetwork Movies
HBOHD - HBO
MAXHD - Cinnemax
SHOHD - Showtime
TMCHD - The Movie Channel
S-HD - Stars HD
24 Total. Subtract four for Peachtree TV, PBS, and UPN for not having any HD programming and Fox Sports South for never being on air. This leaves 20 viable HD channels.
I hope Charter steps up to the plate to offer more programming in HD, especially since they charge extra for it, unlike TW. I also hope they start to strengthen their signal, because during some heavily watched events (like the Superbowl) some blocking (digital signal pixelization occurs).
Yours is very close to my Charter lineup in Birmingham. Unfortunately TNTHD and AEHD mostly show what looks like SD programs stretched to wide screen...sux. Even movies that are available on DVD in wide screen are still shown using what looks like the full screen format stretched to wide screen.
