I heard DirecTV redid their web site, so I went to check it out, and it was much better than before; I created an account and logged in and saw that it showed how much I owed them, what channels I get, etc. I also saw that I could go from Total Choice to Total Choice Plus and get like 15 extra channels (half of them Discovery Channels, plus History International, Biography Channel, PBS Kids, VH1 Classic, and a few more) for only $2 more per month.
So I modified my account and hit "accept these changes" and changed the channel to VH1 Classic immediately and there it was! The Who singing something or other! I know I shouldn't be, but I am quite impressed that hitting a button on a web site can so quickly affect what signals the little box under my TV will give to me.
