Well not even speaking specifically about other magic sites, and kind of .wmv with copyright protection doesn't' work on a mac. Which is lame because you can get Windows Media Player for Mac, but it's a way older version that doesn't support their DRM. Very annoying.
However, I was talking about other magic sites, hahahaha. I got a download from E because I was excited only to realize I couldn't play it. Their customer support is still great though. They sent me the DVD asap.
