Thanks.  What if the receiver has two tuners?  I'm thinking of the Dish 
322 (picture of rear at

), wondering if it could provide input to two PVR-250s simultaneously. 
What's not clear to me is whether you need to have two dishes attached 
before you can use the two tuners.  Also, it appears to only have one 
S-video out...
