I have an MPMoviePlayer, which need to work on all iOS from 3.1 and forward. I modify the showing of controls based on the iOS version but I always use the default controls (i.e. setting control style for iOS 3.2 and 4 models, and control mode for 3.x versions).
A strange issue happens on the iOS 3.2+ MoviePlayer. The Rewind button is displaced some 5 or ten pixels up making it unaligned with the rest of the buttons.
Ok so in this case it turned out that my attempt to change content type and controlStyle didn't turn out very well. One solution I found if this issue appears is to create a completely new instance of the MPMoviePlayer and setting up the controlStyle accordingly...
