Any idea why there is a difference in the codes listed in the manual and the ones on the hi-fi remote site ? I've never found that to be the case before. I could have sworn I had the advanced codes before, maybe through a different remote or method. I am using the 8810 to program my MX-500 and I'm sure I used to have the adnvaced codes before. Oh well, have sent note to ofa support to see if they have anything, failing that I guess I might try jp1 programming, just don't know anything about that yet.
