[mythtv-users] Extremely High CPU with Live TV - Myth 0.17

I have tried with XV enabled and disabled, it doesn't seem to make any
difference. Over the last few days I have also been trying with a separate
backend & frontend. When watching live or recorded tv via a remote frontend
the backend usage stays down around 3-4%. the remote front end however is
up around the 90% mark. So whatever I am messing up in the settings, I'm
doing it repeatedly on different setups.
I'm just following the documentation on the MythTV website whilst
compiling/installing MythTV, so not sure what I'm missing or doing wrong.
