I was quite surprised by how good the '97 SE looks. Since it was never touched by any of the harsh color and contrast manipulation of the 2004 version, it looks much more natural and is easier to watch by far, even with the occasional softness and compression issues. The CGI shots fare far better here than they do in the official versions, and yet again I'm amazed at the ability of LFL to have screwed up their later releases so completely. Well done, guys!
As for the cinema DTS track seeming to 'destroy' the Dolby Digital version, the reason for this is that the laserdisc AC3 is encoded with a DialNorm value of -27, meaning that the gain is automatically lowered by 4 dB during playback. This is non-defeatable on most equipment, so in order to make a fair comparison between the two, you must raise the volume by 4 dB to compensate when listening to the AC3. Once this total level discrepancy has been eliminated, the differences between them are much more subtle.
Most Dolby Digital tracks on home video have traditionally been encoded at -27, and this is the primary reason for the persistent belief that DTS is better than Dolby—we almost always automatically believe that whatever is louder must also be better, especially when it comes to bass levels (our ears perceive bass more clearly at higher levels, so this can fool you into thinking that a mix is different even if all that has happened is that the monitor level was changed). The most recent Dolby encoders now default to a DialNorm value of -31, so there is no gain reduction.
It is possible to change the DialNorm value of an AC3 track without actually re-encoding the audio itself, so if this was done, it would be considerably more difficult to tell the Dolby and DTS versions apart, since they are essentially the same mix in every way that matters. Aside from the bitrate, and a possible slight phase difference in the LFE, they are quite the same.
