        mpeg2 isn't really meant for editing but I'm sure you know that ;)

        I suspect you'll at least want to create closed GOPs using the 
        '-c' option.

        The  GOP size shouldn't matter but I don't know anything about
        Adobe Premiere's allergies.   I know that by default Apple's encoder
        uses closed fixed sized GOPs with a size of 15.   

        To be completely safe I'd suggest trying "-c -g 15 -G 15", if you're
        feeling adventuresome and have some time you might leave out the -g
        and -G and see if Premiere will work with variable GOPs.  

        The advantage of fixed size GOPs is that you are dealing with a known
        and constant unit of time (15/25 of a second for PAL).   You can set
        the size down to 12 and that would give you ~1/2 second resolution
        without too much of a penalty in filesize.

        Cheers,
        Steven Schultz
