New Model DC's
 

Does any body know about the UK Dc machines and the compatability issue with newer models +SB backups, do we suffer from the same problems and the US of A, Uk machines do not have a date on the bottom.

Any help appreciated.

I don't know about the UK models, but my suggestion would be to try a regular ISO image and if it doesn't work (but you can see the files when viewing it in your CDROM drive), try burning it with the newer method.
