Thanks Manichean. Ha, I should have used "overwrite existing duplicate formats". Darn. A tad late now sad to say. I may be a good idea to have the default set to this. I suppose there is no 'retrospective' script that i can run now?
If not, I'll just have to carry on this time, but the option is setup for any future imports. I'm up to "L" titles. :|
I should set aside time to read though all the options.
