While searching at various home cinema forums I found this:

which suggests that although mono should come from the centre speaker, some people prefer to use the front left & right. But I also saw this thread where someone who describes himself as an acoustical engineer says that this can cause unwanted effects.

I wonder which release of The Terminator that is? My NTSC DVD released in 1997 or '98 have basically the same info but instead of the last third segment it just says: "It is compatible with all current playback equipment." The audio on it is actually something so rare as a 2.1 mono track, and it sounds fantastic on my system, if only the video quality was that good. ;)
