I tested this by writing an .iso file to a CD (as a file) and then
comparing it to the original with diff. Diff didn't report any
differences. I think this suggests that there is nothing wrong with my
writer (doesn't prove it though). Your idea was good anyway and worth
trying - thanks. 

I have to start installing array6 now, I have spent quite a lot of time
trying to get the burn verified. It would have been nice to get it done
though - I think it's a rather important thing to do. Very usefull when
you have problems with your installation - at least you know your CD is
OK.

Thanks Colin and everybody who replied.
