You should use player.currentItem.duration

- (CMTime)playerItemDuration
{
    AVPlayerItem *thePlayerItem = [player currentItem];
    if (thePlayerItem.status == AVPlayerItemStatusReadyToPlay)
    {        
        /* 
         NOTE:
         Because of the dynamic nature of HTTP Live Streaming Media, the best practice 
         for obtaining the duration of an AVPlayerItem object has changed in iOS 4.3. 
         Prior to iOS 4.3, you would obtain the duration of a player item by fetching 
         the value of the duration property of its associated AVAsset object. However, 
         note that for HTTP Live Streaming Media the duration of a player item during 
         any particular playback session may differ from the duration of its asset. For 
         this reason a new key-value observable duration property has been defined on 
         AVPlayerItem.

         See the AV Foundation Release Notes for iOS 4.3 for more information.

        return([playerItem duration]);
    }

    return(kCMTimeInvalid);
