Need adv codes for Koss 5 disc DVD model KS2503

[crosseye]

Hey guys I'm looking for a little help. I have an OFA 6012B and I have programmed everything for it successfully up to my DVD player. The code my remote is telling me it uses for the DVD player is 0651, but that code doesn't really control anything but power and volume. My DVD player is a Koss 5 disc progressive scan/surround sound system. I'm wondering if anyone knows the advanced code setup for this system so I can program the other functions. Thanks for any help The Koss model is KS2503.
