I've burnt the file!

After uninstalling both Santa and Burning-Xpress, I only downloaded Santa again.

I fiddled about with Santa for a while today and still got orange people on the burnt dvd.

So, I downloaded Burning Xpress again and went for the slowest speed burn (first and last time I used Xpress, the sound was out of sync.)

Just stuck the dvd on and it's perfect!
