Dvd-V audio encoding rates ? (1 Viewer)

[Manus]

I've been searching for some time for information concerning audio bitrates,ie. which discs are 448kbps Dolby or 754dts etc.Anyone know anywhere where this information might be included as part of a review?
I want to compare some R2 titles that don't seem to sound as good as R1 to see if they may be encoded differently.

Thanks a lot for that Jean , it's just what I'm looking for.I wonder if there is a R1 equivalent too.It's interesting to see that although Gladiator won an Oscar for it's Dolby Digital soundtrack most of the bitrate space on the dvd went to the dts track !
Thanks again,
Manus
