Thanks for the info everyone!
@Kory: I have reproduced the flickering with Driving Speed 2*, that should be enough to prove there is an issue. I will let you know if more evidence is needed.
I also believe I have found a reliable source for the VC-1 decoding issue, but am verifying it with others.
As usual, I will provide an update in this thread when I have new information.
Thanks all,
-Nic
