Only Blu Ray and HD-DVD (bye-bye) are encoded with lossless audio (Dolby True and DTS Master). IMHO, the sound of these lossless codecs is way better than that of SDVDs, redbook CDs and even SACD.
As Ckorody wrote, audio-only BDs are coming slowly. I think the music insustry is waiting to see if consumers will change from SDVD to BDs.
