Hi - after ripping many dvds succesfuuly with makemkv, suddenly I am getting the error message 'Error 'Posix error - Permission denied' occurred while creating' - can you tell me what I need to do to fix this? Many thanks.

Full destination disk? Destination directory requires permissions you don't have, running as the user you're logged as?

That has fixed the problem Woodstock. It's appreciated - many thanks for your help.
