Hmmm. I viewed on "The List" and it looked like there was a lot of HD on 110/119, with all the HD locals on 129 and duplicates HD channels that were also on 110/119. I'm not sure how up-to-date the list may be. Regardless, I'm going with 110/119 and it should be fine since 70% of the stuff she watches is local OTA.
most HD on 110 & 119 is spotbeamed to Hawaii, Puerto Rico or Alaska
If you look at thelist under "Beam" it has to say CONUS. All HD on 119 is spotbeamed to those 3 spots
on 110 the HD is the following (the rest are on 129)
USA, SyFy, TNT, ESPN, HDNet, HDNet Movies, HD Theatre, HBO, Showtime, CI, CBS Sports Net, Planet Green, WGN, Movie Channle, Starz
Snapped a photo...says DPP Twin.
that works. All you'd need then is the separator
