Try using AVQueuePlayer. I am assuming that what you described as a lag, in fact is the pre buffering delay. This should be minimized or actually entirely be gotten rid of when using AVQueuePlayer as that baby will buffer the next AVPlayerItem while playing the current one.

On iOS 4.1 and later, you can use an AVQueuePlayer object to play a number of items in sequence (AVQueuePlayer is a subclass of AVPlayer).
