For the TV, I'd start with the Elite Codes (TV 209). There is a good chance those will do what you need.
For the reciever, try the numbered [PIONEER X] (x being the number) at the end of the list to see if any work. I'd start at 26 and work back.
For the BluRay, try the BDP-94HD codes. Those might do the trick.
If those do not, your next step is to program the component manually. You'll have to learn all the IR from the factory remotes. You might be able to find discretes for them here:
[Link: remotecentral.com] Just a note, you can't add hex to the remote until after you've made a macro. So make a dummy macro. After you have all the buttons working, make your macros. Then tune up the macros.
