By the way, I turned to 508 last night and it was still on -- that's RDS-HD on the Rogers "dial" in Ottawa. I do remember the Info showing "Free preview until ..." before, and that wasn't there. So it would appear that I am getting RDS-HD for "free" -- likely part of the VIP package.
Yee-haw! Now, I wonder if there is any way to take the RDS-HD video and the CBC-HD audio (since Dean will be making the play-by-play, most likely).
Now there's cool (but entirely impractical due to how few times it would actually get used) feature for a set-top box. Combine the video of one channel with the audio of another. This is one practical application, but I could imagine a few hilarious applications as well.
