Dear Neil,
Can you please send a mail to support(at)rc9800i(dot)com, so that I am able to get more information on your problem & hopefully give you the solution?

Dear Urte,
Although the Dreambox brand is in the list, unfortunately this does not mean that also all codesets are in for that type of device. If the "learn & match", "autoscan" and "select & try" options do not work, it is still possible to add a Custom codeset, and learn every button with the original remote ("Select &try", choose "Custom" and you will be directed to the screen where you can learn the buttons).

Regards,
Luuk (Support RC9800i)
