You are kind of all over the map here ozwrongbar. There are a couple of things you can do.
First let's go to YouTube.com (I am going to assume you have an account. If you don't, create one).
Once on YT, scroll to the bottom of the page and select 'Try Something New!'
Select HTML 5 video (Try it out) and join the beta, then choose Feather, and again, join that beta program.
Go to BlackBerry App World BlackBerry World - Player For YouTube designed for the Style

You should be good to go, and yes, I know not all videos will work, but this will give you access to over 90% of them.
