In the lounge I am using the optical out on my motherboard for the audio and letting my AMP decode the audio. In the back room on the server I just use the 2-channel audio-out plugged into a stereo.
Off the server the audio volumes appear to be at more or less the same level. In the lounge different channels occasionally have different levels. 
I have even noticed that sometimes a specific show is at a different level (ie. the crap at the start of the recording is loud and then when I get to the start of the show it is lower or vice versa) and that sometimes AVIs downloaded or ripped are at a different level again.
Looking at the Amp I am able to see what type of audio it is receiving and how many channels it is using (stereo/surround). Australian TV seems to broadcast an assortment of different audio (I notice more surround sound on network Nine) and there appears to be a correlation between the type of audio and the volume levels.
