The way I understand it, you can also add the bit below at the end of YouTube urls to force High Quality viewing.
&fmt=18
As an example, this should work:
http://www.youtube.com/watch?v=abViXCXIXbI&fmt=18By the way, bookmarking your site, looks worth checking out. Only way I found it is cuz my lil labor of love vid link was embedded above.
Check out my channel (DMKPDX) if you're a die-hard Blazer fan though, I'll be tossing up game highlights regularly. They're not professional looking or anything but if you're die hard you don't care. ;)
Anyhow, nice to see a Blazer site doin its thing.
Go Blazers!
