Reducing volume

[Derek Moss]

It's not that unfortunately. They remain much louder than my other
sources (i.e. switching from LiveTV in XBMC on the RPi) throughout.

I tested 3-4 programmes at random the other day and one was actually
OK and about the same volume as LiveTV but the others were all much
louder and I had to turn the volume down quite a bit.

As I say, it's mainly an issue on XBMC on the RPi for me as on Windows
I can use ffdshow to boost/normalise LiveTV so that there isn't such a
difference when switching to iPlayer.
