andy,

I looked at the videos and from what I could see from them, they looked pretty normal to me. Maybe a hint of dysfunction with your left scap. About your doc doing he scan, let him, its his job to rule out structural/ medical issues. As far as tests for the scapula, the ones that i would use would be manual (with my hands). A lot of the time it is easier to feel a problem than it is to see it.

Good luck.
