There isn't a way to blink back advanced codes, mores the pity. I do have the official UEIC button assignment for CD/0000 in the advanceed code section of my site, but as with most UIEC listings, it's kinda confusing. The standard layout has 'next track' on the up arrow button, 'prev track' on the down arrow, and 'next disc' on SELECT. The numeric buttons are track selects, the trasport keys are what they appear, and I think ENTER is the 10+ button.
Personally, I moved the next & prev track buttons to ch up and down, and I put next disc on the MOVE button, then I manually assigned all the functions that I needed for my receiver on the volume, surround and arrow buttons.
Here's a tip for you if you really want to max out that 15-1994 of yours, the P&P device key is really a CD device key in disguise, so you could put your CD player there and use the real CD button for something else.
I have more tips like that on my site.
Oh yeah, I hooked my Sony CD player up to an X10 module to control the POWER, as I have an X10 Home Automation setup anyway.
