All that does is lead to the conclusion that "pass=1" is valid alone,
but "pass=2" requires the presence of either the "bitrate" or the
"quantizer" option - which, if true, would seem very odd to me.

(Not that he'd be likely to get a lot of help right away even if there
*is* a genuine problem, since the lines about frameno.avi reveal that
he's using 1.0pre7try2 or earlier.)

side of it.
