Hmmm... I was only think of the "tuner" you mentioned, not the  
decoder chain.

But think about it, a PVR card in quantity, minus the cost of the  
board, power components, connectors, IR interface, packaging,  
marketing, included software and documentation starts to get close to  
nothing. Granted the TV set might need something better than SD they  
may only do 720P, and if enough of those chips are made they should  
get pretty cheap.

But there would also be an "MPEG Tax" associated with anything using  
those patents I would suspect, that may turn out to be the largest  
part of the cost. I've read that the license fees for a consumer DVD  
player to use MPEG are around $20 per unit, and the cost might go  
higher for anything beyond 740x480.

I guess only time will tell in the end.
