Streaming video from server....Not easy..help would be appreciated!

Question

Dear Developers,
It has been a long time since I have posted on this community - its nice to see some familiar avatars still here.
I have been developing an iphone/ipad app for cancer patients that requires streaming of video footage from a server.  The app is sturctured in a simple tableview with images of a range of videos.  The user selects these tableview cells and the video should then stream.
I hoped to use material saved on a private youTube account - but getting a seamless stream from the Tableview selection hasnt been easy.  It seems that youTube clips must be loaded into a uiWebview and then selected. This feels clumsy.
I have subsequently opted to stream from an alternative server with .mov files. The code I am using is as follows:
NSString *videoURLString = @"https://www.dropbox.com/s/7wmltu14ti91qm9/IMG_0024.MOV";
NSURL *videoURL = [NSURL URLWithString:videoURLString];
MPMoviePlayerController moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];
[moviePlayer prepareToPlay];
[moviePlayer play];
[self.view addSubview:moviePlayer.view];
When I select call this code the movieplayer opens, but the video will not load. I recieve an error warning in the console containing :
CGcontextsaveGState: invalid context 0x0
CGContextClipToRect: Invalid context 0x0
CGContextTranslateCTM: invalid context 0x0
CGContextDrawShading: invalid context 0x0
CGContextRestoreGSState: invalid context 0x0.
What must I do to get this code working ?
I would be very grateful for your help on this.  I am also keen to learn if anyone knows of other source code that would provide a cleaner experience of youtube video streaming.
with thanks.
James

You may use this:
        NSString *videoFilepath = @"https://www.dropbox.com/s/7wmltu14ti91qm9/IMG_0024.MOV";
        NSURL *videoURL = [NSURL URLWithString:videoFilepath];
        MPMoviePlayerViewController *movie = [[MPMoviePlayerViewController alloc] initWithContentURL:videoURL];
        [[NSNotificationCenter defaultCenter] addObserver:self
                                                 selector:@selector(playbackFinishedCallback:)
                                                     name:MPMoviePlayerPlaybackDidFinishNotification
                                                   object:movie];
        [self presentMoviePlayerViewControllerAnimated:movie];
then
- (void) moviePlayBackDidFinish:(NSNotification*)notification {
    NSError *error = [[notification userInfo] objectForKey:@"error"];
    if (error) {
        NSLog(@"Did finish with error: %@", error);
add the MediaPlayer.framework to your project &
add to your .h
#import <MediaPlayer/MediaPlayer.h>
Hope this helps
