Though an approach like this will have issues when running up against
the limits (i.e. 0% or 100%) and can get "stuck" due to rounding error,
depending on the card/resolution of the volume slider.  I posted a
script a while ago (
http://www.gossamer-threads.com/lists/mythtv/users/216149#216149 ) that
handles these and many other issues, and have improved it since (see
attached).

The script I posted will (the current one using either mythtvosd or
xosd's osd_cat).  ;)

You'll need to configure the script by editing the variable values at
the top as described in the comments.
