hi tim.
that sounds like weird behaviour.
have you tried trashing your preferences?
i haven't had the problem you describe, so im really just guessing.
i had some luck shaking other form of clingy metdata recently,
[
www.lafcpug.org]
maybe copy the sequence,
and delete all audio in the copy.
then try the EDL again.
if that doesn't work,
maybe Media Manage the no-audio sequence,
use "create offline" mode
maybe the new MM'd sequence will be OK for EDLs??
just guessing...
