Just a quick follow up to my follow up
.If your box lets you access an on screen menu,tv guide-recordings-search etc,see if you have a audio set-up option.Mine is a Motorola and if you can modify the settings look for a audio compression menu.If it is set to low or off your sound can vary quite a bit.A heavy compression setting will equalize the sound between channels especially if you have 2-tier cable,some analog,some digital.This will have no effect on a digital output but with standard l-r it might make quite a difference.
