Topic: RayDAT 1 & Nuendo Sync Setup - help!

Hello.
Since I went to the RayDAT from my older Hammerfall, I cannot seem to use internal timecode without getting a lot of clicks.
If I use TCO it works (alongside "external clock" in Device Setup) but the instant I try to set the RayDAT as master timecode source it is click city.
This has to be pilot error on my part - in Nuendo 7.1 what do I need to do for the following to work:
A - single bank of ADI-8 DS converters
B - 2 ADI-8 DS converters with the second bank running external hardware.

I just cannot seem to get the settings correct unless I use the TCO option in the RME settings.
Please help - it's driving me nuts
