You could also use TVML and TVMLJS
https://developer.apple.com/library/prerelease/tvos/documentation/TVMLJS/Reference/TVJSFrameworkReference/
Adhere to the 'TVApplicationControllerDelegate' protocol and add some properties.
AppDelegate.h
@interface AppDelegate : UIResponder <UIApplicationDelegate, TVApplicationControllerDelegate>
...
@property (strong, nonatomic) TVApplicationController *appController;
@property (strong, nonatomic) TVApplicationControllerContext *appControllerContext;
Then add the following to 'didFinishLaunchingWithOptions'
AppDelegate.m
#define url @"http://localhost:8000/main.js"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.    
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.appControllerContext = [[TVApplicationControllerContext alloc] init];
    NSURL *javascriptURL = [NSURL URLWithString:url];
    self.appControllerContext.javaScriptApplicationURL= javascriptURL;
    for (id key in launchOptions) {
        id val=[launchOptions objectForKey:key];
        NSLog(@"key=%@ value=%@", key, val);
        if([val isKindOfClass:[NSString class]]) [self.appControllerContext.launchOptions objectForKey:val];
        self.appController = [[TVApplicationController alloc] initWithContext:self.appControllerContext window:self.window delegate:self];
    }
    return YES;
}
create a folder and add the following files
main.js
function launchPlayer() {  
   var player = new Player();  
   var playlist = new Playlist();  
   var mediaItem = new MediaItem("video", "http://trailers.apple.com/movies/focus_features/9/9-clip_480p.mov");  
   player.playlist = playlist;  
   player.playlist.push(mediaItem);  
   player.present();
   //player.play() 
}
//in application.js  
App.onLaunch = function(options) {  
   launchPlayer();  
}
careful with this url in the mediaItem
Set up a template of your choice.
index.tvml
<document>
  <alertTemplate>
      <title>…</title>
      <description>…</description>
      <button>
          <text>…</text>
      </button>
      <text>…</text>
  </alertTemplate>
</document>
open terminal and navigate to this folder then run
python -m SimpleHTTPServer 8000
make sure the port here is the port in your ObjC url. The Apple examples use 9001.

One issue I ran into was trying to play a local video file. It wouldn't work and there were constraint issues etc.
It looks like you can't use python to play the videos so either try apache or link to a video on the web.
This SO answer pointed me there.
