Have backed up loads of discs with IfoEdit and also with DVD Decryptor (ISO mode) and the Region Codes are taken out - how can i put a Region Code back in? It sounds like a daft question, I know, but Panasonic DVD Recorder won't play DVDs without region code 2!!
Use DVD Shrink instead as it gives you an option to include the region(s) of your choice or ALL regions. You don't need to use Decrypter with it.
