The easiest way is to peer around in the files section of this site and see if someone has uploaded a file that has your device in it. If you have a general universal remote (you can get a $5 cheapo from wal-mart that works for most stuff, and most cable boxes can be programmed for other components), you can program that and then use it to learn. Also, if you bought your remote from an authorized dealer, most of them will be willing to work with you if they have the correct codes. Other than that, I am not sure as I have always managed to get things worked out at that point.
