One thing you might check: Look in the Registry
under HKCR\.mts and see what's there. I have it
marked as a video file. I suspect VLC did that. It's
possible that .mts can also be something else that's
hidden by default. (If hiding "hidden" files is enabled.)

Why not just install VLC? I wouldn't put anything
past Microsoft when it comes to trying to push their
own media player.
