What do you mean with "MediaPlayer"? Are talking about a QTMovieView (QTMovieView Class Reference)?
If so, you can get the QTMovie object by calling:
[myQTMovieView movie]
and then get its
[aMovie currentTime]
Please note that this only applies to OS X and not to iOS. Please specify more details about your question.
