There's the key factor there. Networked tuners, meaning the tuner is a 
little embedded computer sitting on your network somewhere, and feeding 
data to you. Networks have unpredictable latency, and so anything 
operating over one must be able to handle it. Hardware drivers do not 
account for such things, and should not account for such things, but 
never the less run into such things when attempting hardware pass 
through in a virtual machine. The result is somewhere between unreliable 
and completely broken. Driver developers typically want to have no part 
of someone attempting to use hardware in a virtual machine.

There are other architectural reasons why the typical user has no reason 
to want to use a virtual machine, but that's a topic for another thread.
