I hope this isn't old (if it is, apologies, I've not been on a great deal recently) and I hope it's not against the rules (if it is, sorry, but I don't think it is).
Anyway,
here you can download Live 8 acts from all the various concerts. They're good quality (so quite large) but sadly they're in quicktime format.
Well, enjoy/ignore accordingly.
