You start to turn the ball high in your downswing.  I used to do the same thing.  I was also off balance at the line and would often step to the side after releasing the ball.

I worked through it by trying to throw it as straight as possible, staying down at the line and keeping my hand behind the ball with a free armswing, no muscling the ball.

After I was able to throw it fairly straight with good forward revs, I was able to retrain my hand turn at the bottom of the swing near my ankle.  I now have better balance at the line, a much more consistent release and have picked up a bit more ball speed to go along with my improved release.  Now, instead of pulling the ball, I more often push it outside my line when I make mistakes.

Now, I am in the process of relearning what different changes in hand and wrist positions do to the reactions I get on the lanes.  

I am bowling this summer in a different house that has slick synthetics with weak backends as opposed to my old house with wood lanes that had flying backends.  After three weeks, my average is plus 8 from my final winter league average, even though my spare conversions have dropped off quite a bit.  I find I am consistently throwing the ball outside on the left side spares (lefty) and overhooking the ball on the cross over spares.  I have to replace my plastic ball and I am going to work on using that for all my single pin spares over the summer.

As already suggested - working backward from the end is a great way to discover  the feeling of what really works -vs- what is really not working.  

1.  What is the position you want to be in when you deliver the ball?  How much knee bend?    How straight is your back?  Is you head up, or is your nose pointed at the floor?  Where is the balance arm? Swing leg position?
Grip your ball and just let it hang by your side.  Now move into your desired final position - find your balance - feel your body in this position - put your hand in its' final position - feel the tension in the wrist and forearm - the feeling of pressure on the fingers - is the finger pressure balanced - do you want the ball ball to feel balanced - or are you wanting to feel the weight of the ball differently?

After finding the delivery position the next step is to learn to get into that position by doing 1 step practice.  Do you remember seeing Tony Reyes do the one step delivery for the skills challenge?  

Hope this helps.

I couldn't view your video as the link didn't work. However, from the advice I've seen you could try aiming for the feel of the inside of your elbow brushing your hip as you deliver the ball. It won't but if you try and press the inside of your elbow so that the feeling is of it brushing your hip, this can help.

i also decided to stay behind the ball instead of turning my hand around the ball, what i did was to focus only on the release

when u r about to release, the fingers are pointin to the floor, and when u let it go, u should feel the ball on ur fingers and the whole motion of the ball rollin forward when u raise ur hand (to put a roll on the ball)

another way of doin it is something similar, when u r about to release, fingers point down and then u "push" the ball forward after the thumb exits, this might not be the best way but its a way to start when it comes to staying behind the ball

When a house bowler misses the mark, misses the break point and strike, for many ppl its called a wallshot. When a pro does that its call adjustment

When a house bowler gets his finger stuck in the ball and fall on the lanes, for many ppl its called lame bowler. When a pro does that its called the Machuga flop! ha i like this one.
