iPad video audio problem

Hey guys,

Not sure if any of you have had any problem with this issue, or comes across it.

I am currently having trouble with videos playing with audio attached. However when audio is not encoded with the video there is no problem with the playback. When audio is attached however, the video will simply not load. The transition will occur, as if to play the video, but will then revert back to initial window.

Just to let you guys know, this maybe an issue with the integration from unity into xCode. I am running this on an iPad 2 and 3 (Both have same issue)

Things I have tried:

All the recommended video extensions (mp4, mov, 3gp...)

The video runs fine with audio within an existing xCode project I have created in the past, both using either the video component to play the video or using the MPMoviePlayerController via code.

I have tried both iPhoneUtils.PlayMovie and Handheld.PlayFullScreenMovie

Any help you can provide would be much appreciated!!

Thanks
