RegEx in Custom Profile Field

[Digital Jedi]

Having only worked with RegExes in AME, I see that vB handles them a bit differently. I want a Regex that matches typical YouTube URLs along with the extra stings that come along with them. I tried my Regex for my AME YouTube definition:

^http://[\w.]+youtube\.[\w]+/watch[\?\#!]+v=([\w-]+)[\w&;+=-]*[\#t=]*([\d]*)[&;10shdq=]*|^$

But vB gives me a preg-match error with the exclamation point in there. Didn't work escaping it, either. AME has it's own quirks with Regex, and that's where I learned how to do them. But I suspect that vB does it a little differently. This needs to match these kinds of URLs:

And deep linking examples.

Or just be blank. Maybe my matches don't need to be this specific?
