Up until this season, only the Sabres home games were in HD and they were on channel 638-1. The SD feed of all games were on 638. Channel 638 (and 638-1) is only used to show Sabres games. I've never seen any other programming on it. But now this season, all the Sabres games will be in HD (http://sabres.nhl.com/club/news.htm?id=538182), so I'm wondering if channel 638-1 is needed anymore. Is it? Couldn't they do away with it and treat 638 just like any other HD channel where depending on the receiver it either tunes to the SD version or the HD version? Same as D* did this year with the Sunday Ticket channels.
