Rob and list. I just discovered another point. While the recorder does not save marks that are read by SR. If I load the file on my computer and place SR marks in the file, then put it back on the recorder, those marks from SR are recognized by the recorder. So I wonder what might be different in SR's ability to write marks on the sony but not read them. No rush on figuring this out. I am curious and it would be nice if it worked, but it is definitely something I can deal with. Neal
