We seem to discuss the visual changes more. It's probably easier to spot and discuss a visual change than an aural one in an internet forum. I see a similar disparity over at the Home Theater Forum. Movies badly remixed or lacking their original mono do not get the same amount of ire a botched video master does.
We've been repeatedly rebuffed when asking nicely that the OOT be released. When we did get it, it was from ancient analog masters that should have been junked, let alone put on a DVD. The years of hemming, hawing, evading the question when the rare opportunity arose to even ask it in a public forum, and the outright baloney from Lucas and his official spin doctors, have left a bad taste in many a fans' mouth. That's enough to make anybody a little bit negative.
A simple inexpensive remastered release of the OOT in HD could wipe that all away in a instant.
I'm hard pressed to think of any other franchise that treats it's fans this way.
