I would not eliminate any mentioned in the poll. My choices:
1. SD clones of HD channels -- HBO-SD, ESPN- SD, etc -- that have the exact same content, just in lower definition. (I am not referring to things like HBO2, which does not have an HD counterpart, or things like Bravo, which has different programming from BravoHD). It was speculated elsewhere that Voom may be contractually obligated to carry the SD versions, but they should try to get those contracts changed to allow them to carry the HD feed in lieu of the SD feed. The contracts may have served a purpose with SD cable and satellite carriers, but they make no sense in the era of HDTV, especially with a service like VOOM that is catering to HDTV owners.
2. The auido-only music jukebox channels, 852-885 (I am NOT referring to MTV, VH1, and other channels that play musically-oriented programming). I don't see a lot of point in these channels; I have satellite radio if I want to listen to music. But I would assume that these channels do not use a lot of bandwidth, so eliminating them may not make much of a difference.
3. MOOV
