I am very thankful you guys have videos in 720p, and I would be content with it not being in higher resolution for a bit longer. However, one thing I would like with my paid membership would be 5.1 audio.
I often view my Whiskey videos on the media center and it sounds weird coming out of one or two speakers. I know it's not really needed, and I know it would take up time...but it would be pretty sweet. If not 5.1, I'd be happy with an upgrade to higher resolution video too. >.>
Keep the commentary in the central speakers while the game runs through the other 4.
EDIT: Podcasts in 5.1 would be nice too, it'd be sweet to hear each person out each speaker and that shouldn't be as hard.
