Hi!
I'm sorry I can't help you with your question, but I've noiced that you have a Pioneer DVR-RT500, well, I have the same and I've lost my remote. Aparentely, my baby put it into the trash can and we didn't noticed...
Could you post the Codes for the remote?
I saw that another person is needing them as well, so you could help him too!!

Thanks in advance an I hope you can resolve your problem.

Virginia.
PS: If you rather send the codes to me, my e-mail is vramunda @ yahoo . com
