Hi, Andy,
Welcome to REBOL. I agree with Gregg: you are way ahead of where I was at
two weeks!
I was already hacking some suggestions when Greggs email rolled in. I took
a slightly different approach in a few areas, mainly as a way to show some
short-cuts. Altered listing follows at end.
From: "Andy Finkel"

Like Gregg, I made the text in the info box match the button height, but I
had also taken out the space between the buttons so that the time line could
more carefully match the buttons.
In addition, I showed a different way to format the time bar. I inserted a
more generic way to make the length of the button match the length of the
show (using a combination of "time" math and pairs). I also turned off
wrapping of the text in the button, in case that would be of some use. I
made a few other tweaks that I don't recall right off, but I put comments
where ever I made a tweak.
Very impressive effort. You'll outclass me within just a few more days!!
Good luck.
