YouTube has some VERY sophisticated software which prevents too uploading copy righted material. a while back I tried to upload a little video I made using A Place Where We Used To Live and it wouldn't let me! I ended up using a live version from Boothbay.
But the point is, if MKs management want to stop these videos, they can... until they do, let's just enjoy them. There is an excellent multi cam from 2010 as well.
