When your going for Bankshot Hustler you don't have to do it all in a row. The best way to do it is do use the 2 controller trick on 8-ball.what you do is put the profile you want to get the achievement with on the 2ed controller and some random profile on the 1st.Then hit the 8-ball in with player 1 50 times and you get the achievement.If you don't have 2 controllers you can do 9-ball and try to get the 9 ball in off the break(which is not as hard as you may think)50 times.As for videos....you don't need em.Just keep at it and you will end up getting it.I never thought I would get it but I did.
