Not sure what you mean by "location". Do you mean I-frames must aligned at
sector boundaries in the multiplexed stream? This is already done
automatically. Do you mean the GOPs (Groups-Of-Pictures) must have a fixed
size and B/P frame structure? Again, what you need is probably already there.
However, I'm puzzled why Ifoedit would demand fixed-size/structure GOPs. It
is as far as I'm aware definately *not* something required in the DVD
standard...
