I think the usage of the term "Up Next" in Channels in regard to older recordings is quite useless. It is also confusing to anybody that doesn't use the DVR on a regular basis. Since not everybody watches things in the order they were recorded or even close to it, "Up Next" doesn't really even make sense in that context.
How about simply calling it "Recordings". This would work while "Recent" serves the purpose of identifying the most recent recordings.
I think a DVR should at worst be intuitive, and "Up Next" is far from that.
Thoughts?
