Thanks everyone for your help.
I haven’t found the answer yet though.
We’ve got Vegas 6c running on 2 PC’s, and both PC’s have exactly the same problem: the image doesn’t appear on the TV’s connected to the 2 Canopus AD/VC100’s.
-The switch is set to digital input
-We don’t have Vegas 5 and 6 running simultaneously
In both cases Vegas 5 work fine, but not with Vegas 6.
In both cases they recognise the connected device…
Aaargh. Sometimes one misses analogue video (although only for 2 seconds).
