[mythtv] backend emitting copious mpeg2video logs, even with '-v none'

[buzz]

my backend keeps emitting copious mpeg2video logs, even with '-v none',
and it's really making it difficult to find meaningful data.  I know I
can do a 'mythbackend | grep -v mpeg2video' , but can I just turn it off
properly?  
I'm guessing I've just missed something somewhere, and need it pointed
out..?

start of backend log follows:

# mythbackend -v none
