I'm so glad I found this thread! I just purchased a Cinema 7 Learner after reading all the reviews and was amazed that I was able to get every function I wanted for my Sony TV and Panasonic VCR without ever even resorting to using the learning ability.

Then I got to my RCA RC5231Z DVD player and was a little disappointed. Power, Left, Down, and FF were the only 4 keys working and 0522 was the only code for RCA DVDs. I wasn't sure what to do and then saw this thread tonight. Sure enough, I just walked out to my living room and if I point the remote 90 degrees away from the DVD player, every key works!!!

I tried building up multiple pieces of tape over the IR receiver and it helped, but I got to 12 pieces of tape and still couldn't aim directly at it. So I peeled them off and for now will just aim away. Now I'm off to test some of the Advance codes from starbase314 to get a couple other functions working.
