Have you actually watched the Voom channels ? Despite the propaganda from the providers who don't have them, the content in the Voom channels is actually better than the other HD channels.
Rave-HD has HD recordings of live concerts. New material debuted this weekend, so don't believe the "only repeats" comments.
Gallery-HD has art shows, and nothing improves more from SD to HD than art (it's almost like you are in the room with those masterworks, without the $2000 air fare bill).
Ultra-HD is fashion shows, which will appeal to many female family members (or males that like pretty but skinny chicks).
Rush-HD has extreme sports and WorldSportHD has international sports.
Monsters-HD, KungFu-FD, FilmFest-HD and WorldCinema-HD have horror, martial arts, indie, art-house and international movies, all in HD.
Equator-HD has travel and nature shows, Treasure-HD has programs about collecting things, and Gameplay-HD and Animania-HD are self-explanatory.
Most importantly, it's all True HD 24/7.
In contrast, A&E-HD, NationalGeographic-HD, TNT-HD, ESPN-HD, and ESPN2-HD have lots of upconverted SD programming. Just to show you how bad it gets, A&E-HD are showing "24" in SD and 4x3. Even the DVDs of "24" are 16x9, so A&E-HD couldn't even bother renting DVDs of "24" in order to at least give you the whole wide screen of the original. Even worse is TNT-HD which stretches 4x3 SD programming to make it fit the HD screen, distorting the image.
FoodTV-HD and HDTV-HD are 24/7 HD, but in order to do that, they have to show a tiny fraction of the SD channel's programming (eg no Emeril).
