If you're wanting to use MediaPlayer object then the following calls will work for you:

MediaPlayer mp = new MediaPlayer();
mp.setDataSource("http://www.youtube.com/watch?v=SgGhtjKWLOE&feature=feedrec");
mp.prepare();
mp.start();

Otherwise, if you don't mind having the YouTube app take over, you can use the following code:

startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.youtube.com/watch?v=SgGhtjKWLOE&feature=feedrec")));

Uri uri = Uri.parse("http://www.youtube.com/watch?v=SgGhtjKWLOE&feature=feedrec");
Intent i = new Intent("android.intent.action.VIEW");
i.setDataAndType(uri, "video/*");
startActivity(i);
