I have some cheap movies from Asia which I wish to back up. With movies I have purchased here in Australia I haven't had a single problem and normally use DVD shrink then DVD clone. Unfortunately if I use DVD Shrink (current version or previous) I get the error "Invalid DVD navigation Structure". If I try "reauthoring" the movie it shows the main movie file in the browser to be only 25kb?? For those movies which are small enough I tried using DVD Decryter which will write the files to my hard drive but it saves the file type as an unknown filename extension which will not play as a movie nor burn to media. Would appreciate any suggestions as to how I could back these movies up! Sorry if i've posted this in the incorect forum but I I had posted it in the newbies section and not had any response!
