I have the same problem which I noted in my post on Mar. 10, 2004
and titled "Sound difference M179 & PVR-250"

I "solved" my problem on the front end.  On the Main window choose
Setup.  On the Setup window choose TV settings.
Go to Recording Profiles and choose the MPEG-2 Encoders.  Then for
all items in the list (default, live tv, etc) I went to its Audio 
Quality page.  Set the Volume(%) to 100%.  This way Myth will
set the volume on the PVR-250 to 65,500.  My M179 output is stuck
on 65,535.  But these values are close enough that I don't notice
any volume difference.

You can now use alsamixer (if you use alsa) and/or mythfrontend's 
volume keys ( "[" and "]" ) to adjust the overall volume.
