So I actually set-up my Onkyo 905 remote with SkyHD and Panasonic PZ85b last night. I got a leaflet with the remote codes when I bought it, havent got that with me at work though. Did yours not come with a leaflet? If sky was not under there try looking under Thomson. The Panasonic code was the last code in the leaflet under Panasonic.
One thing to mention, the SKYHD code doesnt set-up the different colour buttons (Red, Green, Yellow & Blue) so you will need to change some of the functions of the other buttons using the learn mode.
