Thanks Mark,

That's helpful to know.


Regarding my buffering/stuttering issue: I've not had a lot of time to 
test, but it appears that even though the buffer is still at 0% when 
first changing channel I rarely notice problems with playback.
I'm in an area with strong TV signal - I imagine that helps.

When I've got time in front of the TV, I'll turn on verbose logging 
again to see if there are A/V sync issues or audio buffer problems like 
I'd seen once before.

Thanks,
evade.
