I may be wrong, but can you get channel numbers, epg name and data without having to tune to those channels? Isn't there like a system table or something.
I found this post on here that shows the MPEG4 STB with the program guide up and several channels that may be the MPEG4 channels.

It also shows Starz HD which was MPEG4, but the browse banner isn't up at the same time telling you what channel that is... So it may or may not be 9985 ETC5
