audio quality

BD audio is a step up from DVD audio for a few reasons. Even if you can only use the lossy soundtracks on a BD, DTS is usually at the higher 1.5Mb/s data rate and Dolby Digital is usually at the 640kb/s data rate. Each of these are higher than their DVD counterparts: DTS on DVD was mostly at 768kb/s and Dolby Digital was mostly at 448kb/s. If you can use the advanced codecs offered by DTS (DTS-HD Master Audio) and Dolby (Dolby TrueHD), you are getting a soundtrack that is nearly always equal to the master PCM soundtrack that it was sourced from.

Now, I used the words usually, mostly and nearly always for a reason: there are some douchebag studios *cough*Warner Bros*cough* who will at times release lower than expected quality for the audio on their releases (yes, even for recent BD releases). But for the most part, the studios tend to give you better quality, not worse, so BD is more often than not a step up in audio quality.

As for a DVD list of similar, there exists one at AVS Forum in the section for DVD movies, but I would guess that by now it may be in the archives.
