So I think I got really lucky here... I bought a South Park episode like 5 days ago, and it didn't work on my macbook/ipod. Anyway, i sent a complaint to Apple explaining my situation, and they credited my account "1 Video Credit". So I went and bought the latest SP episode, and it worked of course. SOOOO...the video credit is still there. I bought another 2 episodes of Lost. Still there and my account has not been charged. I have waited two days and nothing has happened. Just tried another 2 episodes... Still there... So do you its just a bug??? I like it.
