Mike,

Even though this doesn't solve the problem, I'm sure every little bit
helps.  With that in mind, I've learned something interesting.  (At
least I think it is)

Rehash:
1) The HD file I'm watching was recorded from HDHR in the 20-fixes
branch.  It played louder under 20-fixes (I think)
2) I've since compiled the SVN trunk and started to notice the drop in
volume when playing back the HD content.

Interesting part:
1) I play the file using mplayer (with no other volume changes) and it
is just as soft as mythtv.
2) I play the file using xine (defaults) and it is much louder and clearer.
3) I play the file using vlc (defaults) and it is louder as well.

I'm not sure if myth uses the mplayer libraries during compilation, but
it may be related.

Here are some of my system particulars:
