Axiom Home Page Forums General Discussion Home Theater Need Help with audio issue

I also have FIOS and find that the dolby 5.1 HD channels volume
is much lower than the SD non digital channels. When I switch
to SD from HD it knocks you out of the chair. The STB box I
have from them has an audio compression menu item. This can be
none, light or heavy. The heavy setting helps, but can flatten
out some content.
