Can't download from Match history

Hey all, just a quick question: I'm a smalltime YouTuber trying to upload some games to my channel. On my laptop I can download any of my last 20 games and review them normally, however I can't do the same for my buddy's computer (where we do all the editing and uploads, since my laptop can't handle HD), even for games played on that computer. Is there a local save for games I download for review, and if so what's the standard drive path? And if there's not, is there any workaround you guys know of for me to send him my games?
