Let me guess - you're trying to encode HD material :)
You realize that mpeg2enc is a [EMAIL PROTECTED] encoder, right? ;)
The larger
frame sizes and higher bitrates belong to the higher levels - [EMAIL
PROTECTED]
as I recall (reference books are at home).

1.6.2 had a bug that effectively made it impossible to do what you're
trying to do (--no-constraints didn't really do anything). If you're
running the cvs version (or the 1.6.3-RC2 release candidate - soon to
be replaced by RC3) then you can *force* mpeg2enc to do something
it's not designed for (and as the comments say "may expose bugs" ;))
with "--no-constraints". NOTE also that you'll need to increase the
VBV with "-V" - a value of 488 is sufficient up thru HD rates, so
"-V 488" (and you'll need to give the same value to mplex later
on with '-b').

Not that I am aware of.
