I started asking why you could not see ALL channels in the "all Channels" of the guide about 6 years ago, I never did get an answer, in fact 90% of Level 3 Techs at Express Vu said you DID see them all, only after asking them to view an actual receivers guide did they concede the point.
Still I am sure they have no idea how to rectify.
And I agree, if I saw all the Movie Channels, etc and the films they were showing it might make me more inclined to subscribe.
