Bright House offers 2 local networks,(ABC & NBC). No CBS, no Fox. They also offer INHD 1&2, HDNet, HDNet Movies, TNTHD, ESPNHD, and Discovery HD. They occasionally have Fox Sports Network programming and PPV HD.
I decided to try VOOM for a few months while they had their free installation offer. They have quite a few exclusive channels in HD, but they aren't necessarily to everyone's taste. They don't have INHD or HDNet, but they do have TNT, ESPN, and Discovery all in HD. They also carry Universal HD (formerly Bravo HD). If you order the premium movie channels, you get more HD than Bright House has. In addition to HBO & Showtime, they also have Starz, Encore, Cinemax, and The Movie Channel in HD. They will also attach an antenna for local HD but it doesn't do that well on the CBS station. If you don't want the premium channels then Voom might not have more to offer than Bright House unless you like their exclusives.
I decided not to try DISH or Directv because their offerings seem relatively limited right now. Future satellite launches may enable them to expand greatly.
I'm hoping that Bright House carries CBS and Fox in HD soon, but.....
