The pvrusb2 driver implements the mpeg control API that Hans created 
last summer.  It's had this implemented since the API first appeared.  
So assuming that MythTV is controlling things correctly, then it 
_should_ be working.

One thing you can do to check things a bit - after you think MythTV 
should have set your desired bit rate, use the pvrusb2 driver's sysfs 
interface to inspect the current bit rate.  It should match.
