Answer 1

This is all explained in the docs... also behaviour various between iOS versions.
Do not call gotonextview from viewWillAppear. Instead register your view controller as an observer for MPMoviePlayerPlaybackDidFinishNotification and MPMoviePlayerDidExitFullscreenNotification in viewDidLoad with gotonextview:(NSNotification *)notification as the selector.
Also, I would suggest you launch the movie player from viewDidAppear rather than viewWillAppear.
EDIT: Adapted original posters code (untested)...
- (void)viewDidLoad
{
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(gotonextview:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(gotonextview:) name:MPMoviePlayerDidExitFullscreenNotification object:nil];
}
-(void)viewDidAppear:(BOOL)animated
{
NSString *urlStr = [[NSBundle mainBundle] pathForResource:#"3idiots.mov" ofType:nil];
NSURL *url = [NSURL fileURLWithPath:urlStr];
videoPlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
[self.view addSubview:videoPlayer.view];
videoPlayer.view.frame = CGRectMake(0, 0,768, 1000);
[videoPlayer play];
}
-(void)gotonextview:(NSNotification *)notification
{
NSDictionary *notifDict = notification.userInfo; // Please refer Apple's docs for using information provided in this dictionary
secondview *sec=[[secondview alloc] initWithNibName:#"secondview" bundle:nil];
[self presentModalViewController:sec animated:YES];
[sec release];
}

Answer 2

One option is:
Use a tabBarController with two tabs. Place your video in one tab and place your "second view" in the second tab. then use
self.tabBarController.selectedIndex=2;

Answer 3

The better way is to use a Timer or register an event listener to the video player.
