Personally I think there's just something weird going on, somewhat like a forced upgrade - that makes it so you either can't play DRM protected videos or you'll have the newest IBX version.

iTunes did something similar back in the days of JHymn, you needed version 4.9 for the program to work, so they basically forced you to upgrade to version 6. If you were on 4.9, it would "mysteriously" error until they changed it to a message saying "you need to upgrade".
