[AG-TECH] AG2.2 replacement for setupvideo.py

[Osland, CD (Chris)]

Ivan,

I completely understand that you can't test everything.

We're just in the process of getting some new hardware in
which we can test things - at present I don't have a machine
in which I can load 2.2.

We'll be in touch when we can.

Cheers

Chris
