No you cannot delete or change the channel listings on a VAST box. They are allocated as per your registration location.
I have a UEC 4639 on Tasmanian bouquet & get a duel listing for Imparja South on channels 9 & 91. Don't get GWN7 so can't help with what is normal for that channel set.
When recording channel 9 both channels show a red recording icon; however only one program is recorded in the Playlist of the recording library.
Hope that helps.
