Hey Chris,
Did you ever find the codes for the Yamaha RX-SL100 and DV-SL100? I have the same system and I've been hunting unsuccessfully for any remote codes. I bought the system from Best Buy, it was a floor model without the remote, so I don't even have the original remote to learn from. I could buy a replacement remote from Yamaha for $50 ... but that seems unnecessary. thanks in advance for your help.

Nate
