I have come to simmular problems when doing EDL’s and having the Avid open. Try this, as it works for me. Shut down the Avid and open up the EDL manager. Go to File / Open and direct it to your Bin which contains the Sequence you want to generate the EDL for…
HINT ( make a new bin and insert a copy of the sequence you want to EDL )
once you have done so it should generate the EDL for you.
