Back of the BD says
DTS MA (Theatrical Version Only)
I have yet to actually put in my player though.

Perhaps, in that case, it was easier and/or cheaper to not do a lossless encode for the additional scenes.

Gizmo

Considering each version of the film runs 2.5 hours or more...yeah. Sucks though they gave the Theatrical lossless when more people would (probably) watch the Unrated first.

Gizmo

Ok, nevermind. I popped the disc in and both cuts have DTS MA. The "Theatrical Only" applies to a French DTS Track. The back of the case is a bit misleading.

Supermallet

Well, there you go. Now I definitely think they're using seamless branching.

Gizmo

Yep, it appears so as "The Strangers" just arrived and both cuts are on a BD25 disc (with DTS MA). No way could they do two different encodes and two different DTS MA tracks on a BD25 with special features.

HD Digest says Knocked Up used seamless branching. Unlike WB, Universal actually uses seamless branching on BD.

Wasn't there a time where they couldn't do seamless branching or was that a limitation of HD DVD?

Mr. Cinema

That was HD DVD. Blu-ray has never had a problem with sb.

Both formats can do seamless branching, as evidenced by Blade Runner.
