woohoo, it worked!
the reinstall stopped the advanced display controls from crashing - however, I then had the problem of it being in black and white still. I tried all sorts of pal output formats, and then discovered controls for telling the program which output plug I had the TV plugged into.
First of all, I tried telling the truth, and told it the output was going from the s-video out. That didn't work... and I thought I had been wasting my time
Then I decided to lie to it, and told it that the output was coming from the composite, and, hey presto - I have colour output, but no idea why. Maybe I have misunderstood the way these things work, but never mind
