So I rented a movie off iTunes on my MBP at work because they have faster downloading than at home (500k/sec vs 120k/sec at home). I wanted to play it on my iMac so I transfered the movie to my iMac, imported it into iTunes and it wouldn't play. I get an error message saying this movie was authorized to play on another computer or device. Yes, I did reauthorize the iMac and I still get this error message. Has anyone else experienced this? If so, this totally sucks! I can't download movie at home and I'd prefer not to watch them on a 15" screen when I have a beautiful 24" widescreen sitting on my desk. Needless to say, this will be my last rental from iTunes if this is infact true! BTW...yes, both the MBP and the iMac are using the same iTunes account. I've never had any issues doing this work TV shows, music, or podcasts.
