How to change remote settings at Hauppauge remote?

[Zodac]

Hi,

is it possible to change / add a function at the Hauppauge 45 button remote?
I need the F7 button (Aspect Ratio) at the remote because i have a widescreen TV.

Everything else is fine with the remote!

Thank you in advance.

if you don't use the 'direct access to hauppauge'-settings you can edit irremote.ini

i did remap the 'mute'-button of the the remote to F7 (aspect ratio) since i normaly mute the sound on my 5.1 receiver, so i don't need one on the remote.
