Ok I have 4 files, (Attached)

One file is when I have switched the box on, but not started mythtv at all, 
the next is after I have started the front end, the third is after I have 
gone to livetv for the first time (and have no sound) and the last is when I 
have exited livetv and the gone back to livetv.

The change comes in when after I have gone into live tv for the first time, 
but doesn't change between the times that I go into livetv.

The differences from "diff switch-on.txt livetv-first-time.txt" are...

< bitrate     : 8000000
< bitrate_peak: 9600000

How ever theres no difference between the last two...and mute does not change 
at all....
