Save the The Stream From URL

Question

In my project I am connecting a url and I am watching a video with MPMoviePlayerViewController. But that is not enough to me. I also want to save the file to my Iphone. I have to buttons. one is watch the video, the other is save the video. When I push the button watch I am watchng it. But unable to save it. by this I want to be able to watch the video later. So in another view I want to see saved videos etc. Is there any one can help me or can show the way ? I have tried following code phrase but When the code started, It works for a while (probably it is the download time), but when it is time to save I get Bad EXC_BAD_ACCESS error .Thanks every one.
Here is my code .

CFStringRef *docsDirectory =  (CFStringRef)[NSTemporaryDirectory() stringByAppendingPathComponent: @"recordedFile.mp4"];


NSString *temPath=NSTemporaryDirectory();
NSString *tempfile=[temPath stringByAppendingPathComponent:@"recode.mp4"];


NSLog(@" DOSYA ADI MADI %@",docsDirectory);


NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error = [[NSError alloc] init];

[fileManager removeItemAtPath:docsDirectory error:&error];

NSURL *url = [NSURL URLWithString:@"http://video.teknomart.com.tr/3-13-2.mp4"];

NSMutableURLRequest *liveRequest = [[NSMutableURLRequest alloc] initWithURL:url];
[liveRequest setCachePolicy:NSURLRequestReloadIgnoringCacheData];

[liveRequest setValue:@"headervalue" forHTTPHeaderField:@"headerfield"];

NSURLResponse *response;
NSData *myData = [NSURLConnection sendSynchronousRequest:liveRequest returningResponse:&response error:&error];
NSData *myData2 = [NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://video.teknomart.com.tr/3-13-2.mp4"]];

NSString *myString=[[NSString alloc] initWithData:myData encoding:NSASCIIStringEncoding];

NSLog(@"gelen sey %@",myString);

[myString writeToFile:tempfile writeToFile:tempfile automatically:YES encoding:NSASCIIStringEncoding error:nil];

 [myString release];
return true;
