I agree, it's a very fine line. I'd argue that making something publicly available to anyone with an internet connection vs. inviting friends over to watch a fight is on two far apart sides of this line. That's just me.
Technically, yes, if it can be proved that your friend knows that you don't have the legal right to make the copy and distribute it to him / her. Copyright law is not usually strictly enforced, which in my opinion leads a lot of people to completely disregard it. If you want to disregard it, I don't really give a damn (I got out of the music industry years back, so it's not impacting my paycheck anymore.) But to pretend it's legal is another thing altogether.
