The DA-20mkII can override SCMS code limitations. SCMS (Serial Copy Management System) was designed for consumer DAT recorders to thwart pirating of copy written material. Of course, SCMS doesn't consider who owns the copyright. So if your recorder cannot override SCMS codes, you may also be prevented from copying material that is public domain, or material that you own. Since the DA-20mkII can override these codes, this won't be a concern.
