Yes, priority has no effect on which card starts up in Live TV.  In  
fact, I'm glad it doesn't.  I always want to record from my HD3000  
first, so its the highest priority.  But I never want to start Live  
TV with it (too slow and was problematic in the past if a channel was  
off the air).  So I deleted all my cards and readded them with the  
HD3000 last.  It was a less painful move than I expected with no real  
down sides.
