DTS originally promised VBR on DVD (in 1996-97) but couldn't make it work. Wonder what ever happened to that one.

Keep in mind it also rolls off frequencies above 16kHz, something 1.5Mbps DTS doesn't do. It's just not as efficient as DD. If it was truly "better" then DTS should go below 448 and sound better, much like AAC is better than MP3 at lower bitrates. Truth is, they can't.

Ahhh, I see now. Thanx!
