I am certain it's .20, as it was a fresh compile of .20 on the exact
same hardware and OS install. Nothing else had changed.
I did notice that the sound drop out problems I was having were not
quite as bad with the last version I tried (I'm using .20-fixes), and
that was a few revs ago. When I get a chance, I'll try the latest one I
have (11326 as of this writing, I see that 11327 was committed a bit
ago), and it seems to address the OSD always being drawn issue, which I
never noticed before.
.19 does reflect about 10% more CPU usage when viewing one particular
channel, so if .20 does require more CPU, I may be stuck with .19, or
trying other more expensive options (splitting the BE/FE, buying new kit
to give it more grunt, etc).
