The InfiniTV tuners are a bit of a special circumstance, in that they
are not actually tuners, they are network cards. The actual tuner
hardware is placed on the far side of a local network built into the
tuner, with the USB device acting as a node on that network. MythTV then
communicates with the tuner hardware across the network. It's a bit of a
screwy configuration, but it does away with complications of trying to
secure the device against users trying to do evil things like breach the
DRM.

While it does mean you no longer have to deal with finicky tuner drivers 
across the virtual machine abstraction layer, it also means you do have 
to deal with finicky network drivers across the virtual machine 
abstraction layer. Whether that makes things easier or harder, I don't know.
