Blooper reels and other extra content

I know we need licenses to show the Firefly episodes, but what about the blooper reels and other things, like the River Tam Sessions?

We're trying to find extra stuff to show at the after party, so I thought I'd check in about this.

Thanks!

anything on the dvd as "extras" is off limits.

however the river tam sessions was an internet viral marketing thing, so is ok as far as im aware.
