Ok, so I've been given a DVD from Poland, which my friend's dad has tried to watch here in the UK but his DVD player is having non of it. I've copied all of the files in the folders VIDEO_TS & AUDIO_TS (appears empty) onto my mac but I've no idea what to do next. I have an external HD I can plug in, but I'd like to copy the DVD as near to the original as possible without having to reset or remake all the menus & title screens. How do I go about this? Thanks.
