Comment (by rogerdpack):
Appears reimar is right.
$ file sintel.mpg
sintel.mpg: MPEG sequence, v2, program multiplex
$ file sintel.copied.mpg
sintel.copied.mpg: MPEG sequence, v1, system multiplex
$ file sintel.copied.vob.mpg # with -f vob
sintel.copied.vob.mpg: MPEG sequence, v2, program multiplex
So...I guess either make mpeg v2 the default somehow (which might be nice
for newbs like me), or big warnings, like remair mentioned in comment
16...
Let me know if/how things progress either way.
Thanks.
