I've experienced this many times.

Could you check if the high-res video really needs clicking the
"HD" button or is used anyway ? I'm not sure about this cause
all these "HD-ready" videos do look high-res to me even before.

I'm not sure about this too, for a quick test you may link that video
from testsuite/square.flv and use
testsuite/misc-ming.all/NetStream-SquareTest.swf to check if it works.

My gut feeling is that the problem is in handling the mechanism by which
the "HD" button switches to another movie.
