That is the exact reason for TV Out.  Without being able to ensure that a 
macrovision protected incoming video stream is also macrovision protected 
going out it could be viewed as ATI releasing a macrovision circumvention 
device (or helping others create one).  That might put ATI in some hot legal 
water.  There are similar things with DVD decoding that ATI must protect so 
I understand fully if they want to be overly cautious.  Their core business 
depends on it.
