Hi ShauC,
Sorry for the late reply I have been on a VMWare course all this week. I have one 2400i and one BlackgGold (total of 3 tuners).
The way that I did it was to export: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Service\Video\Tuners\{GUID}\UserSettings\
and then change the {GUID} to the unconfigured card by editing it in notepad and doing a find and replace. Once I did this I then double clicked the reg file and imported it that way.
It seem to work fine for me. Hope this helps :o)
