Hi, I am trying to get my universal remote to control my Onkyo DR-UN7 "executive" stereo/dvd player, but I can't seem to find the correct manufacturer's remote code. I have tried 0792, 0503, and 0222 to no avail. Does anybody know what the correct code might be or where I can search for it? Obviously, I have tried the Onkyo web site and the site for the remote control, which is where I got the codes that I have tried thus far.
