One thing I have to say is that the DVD5 that's been released is not nearly as bad in motion in real-world situations than it looks on, say, a solid 23" 1080p monitor at close range, or in stills. But the 448kbps track, even fixed, sounds, to me, significantly worse than the 640kbps one, which surprised me a bit. I actually got scared that I released the wrong DVD to the spleen (even though it was labelled h_h 5.1 fixed on a.b.sw) so I went back and listened to the fixed AC3 that hairy released yesterday or the day before to make sure, and lo and behold, the DVD matched the released track. It's really a shame about the limitations of the DVD format, because the lossiness of AC3 at less than max bitrates per channel is really on display here
