One of the most common things I get asked for is the settings I use to control the Foxtel Digital STU from MythTV. Well, since the set top unit is almost directly compatible with the Sky Digibox used in the UK for a longer time than Foxtel Digital in Australia, we go to them for the remote codes. The link in the post header has the remote codes (click the 'hand-tuned LIRC config file' link) that I use successfully.
However note that the codes use the Sky terminology for the buttons (which you could change), for example the FOXTEL button = SKY, BACK = BACKUP, and our SETUP button = their TEXT.
Hope this helps.
