Samuel,
As an interested party, I'm keeping my eye on your developments. Can you just confirm that you used the Mconfig program to add the Edge as a source, and as a matter of interest, what name did you give it?;
Adding the Source with MConfig
Add a Generic DVD Player (this will be your modified BD Player or Edge).
Choose OK (don't worry that it does not have the right connections)
Choose No (Advanced)
Choose Next (e.g. Leave it as Connect to G68ADV)
Choose New button next to the From:
Change Type to Multichannel Digital
Change the From Dropdown Box to Multichannel Digital
Optionally change the To dropdown to MD1, MD2 etc.
Choose Connect Button
Choose Finish
Cheers
Mike
Problem is he has a 568.2mm and the details are slightly different.
I think if he just tells the system to add a 598 player and plugin the edge instead it will work.
But someone with a 568.2mm should jump in here.
I'll update Wiki for 568.2mm when I see the details posted.
