These tracks don't use DRC or Dialnorm, so there's no level adjustment being made at any point. This might not always play nicely with non-5.1 setups, unfortunately, but I don't really approve of compromising a mix for the sake to hearing it through television speakers, as commercial AC3 tracks often seem to do. What recent Disney dvd's have done--and what all dvd releases should have always been doing from the start--is to include a dedicated 2.0 mix as the default track, so that people without home theatre systems can simply 'plug and play' and get an appropriate audio track, and have the 5.1 mix selectable for those who can take advantage of it.

With non-defeatable DRC applied to 5.1, and lacking the option for a stereo or DTS track on many discs, there is often no way for users with powerful stereo systems (such as myself for a long time before I could complete the surround setup) to hear the full dynamic range, which can be rather frustrating for those who enjoy that sort of thing. I don't know exactly what kind of equipment corellian77 has, so I can't comment with any greater specificity on the issues he is hearing. Though of course, it could be that he simply doesn't like the way it sounds, which is another issue altogether. ;)
