How to adjust default remote control buttons for hauppauge grey remote?

Howdy. I'm trying to find the right forum for this. Is this the best place for remote questions, or is there a better place?

I already had mythtv working on my htpc, and it took me a while to map remote keys to keyboard keys in .lircrc.

When I setup xbmc, I was impressed that xmbc eden 'just worked' with my hauppauge remote, using default devinput mappings.
I happen to have this remote:

By reading the docs, I did find
http://wiki.xbmc.org/index.php?title=Rem...ol_Reviews
http://wiki.xbmc.org/index.php?title=Remote_Controls (it mentions Remote.xml but there is no such file)
http://wiki.xbmc.org/index.php?title=Keyboard.xml
but it's not super clear how I can get a default mapping of how my remote keys are used, and modify that.

If I want the rewind button to do jump back 10 seconds and now REW, how can I do this?
I'd also love to map the back/exit button to ESC so that 'exit' lets me exit the current video as opposed to rewinding it a few seconds like it currently does.

Also, I have a harmony remote, which I can reprogram to be an MCE remote if need be, but is there a point?

Thanks,
Marc

in windows 7 i customized the remote settings in c:\windows\Irremote.ini
