What 'mpeg2enc' command does transcode generate for you? transcode
isn't doing the encoding itself as I recall, it runs mpeg2enc as
a subprocess.
I think transcode was/is using "-f 3" (generic MPEG-2) rather than
"-f 8" (DVD defaults). The 'generic' form used 'cbr' where the
DVD setting enabled 'vbr'. That was changed to be 'vbr' for both
unless '--cbr' (or -u) is given. That's what I had in mind when I
suggested using the cbr option.
Is transcode doing any extra/different filtering than when you run
mpeg2enc yourself? If so that would be another area where difference
would come in.
It should be possible to use the same options ('-f 3 -b xxxx' and so
on that transcode would generate, but that's just a guess. At that
point the output should be the same (one would hope ;)).
