Sonys are pretty decent for having Advance Codes. I looked and nothing is listed for this, but that doesn't mean it isn't there. I searched for Advance Codes on my Sony DVD changer and found plenty not listed on the web sites. So if your serios about finding out, buy a Cinema7 or Radio Shack remote and search for it..
