I have a Harmony remote in the house so I just loaded the IR4PS3 codes into that remote and just taught the MX-3000 all the codes. However, even Harmony's database for the IR4PS3 does not have the Select, Start and PS Key codes in their list. And just like URC, the Playstation 3 codes listed in Harmony's database do not work either. I'm just short about 5-7 codes including the 3 important ones I just listed.
