I use the web interface for most of my scheduling and series pass creation, specifically the On Later page, and I often find myself clicking More Airings just to see what channel the show is on. (Like it or not, channels have different reputations and can influence whether I think a show may be worth recording.) I also think that channel name is a very basic piece of information that should be on the Calendar page as well.
