Yep, ok - I agree with the interpretation of the mpeg spec in the email thread
(I missed that clause previously).

In terms of DVD vobs, I guess the problem is that Pan & Scan is an optional
output mode, and is the only time that the sequence display extension is used. 

As mentioned in the thread, DVDs do have access to other information about the
display mode, but this is only (I think?) stored in the .ifo files, not in the
.vobs.

I can't see any way to automatically adapt libmpeg2 or mpeg2dec for these
streams and still have it work for ones that match the MPEG spec.
