Sure, it would be nice if they were on BYUtv in HD, but I cast it onto our TV and it comes up fine. Considering the funds they're working with, I'm surprised they're able to do what they do (replays, for example).
I still think BYUtv needs to get with the program and broadcast rugby. If they can find a place in their budget to broadcast BYU Sportsnation every day, they can broadcast a few games a year (Wasatch Cup and Varsity Cup games, at least). The YouTube thing is great, though.
