Hi I have tried to back up "Silence of the Lambs (special edition" using dvd shrink 3 beta 5 & Nero 18.104.22.168. I have followed the step by step instructions from http://www.chrismccann.co.uk for both. However when I try to play the dvd on the PC the movie will not load, I have to point the player to the vob file so as to play (plays great). & on my standalone I get check disk error. When I loaded the burnt dvd back in to dvd shrink I get a "Invalid Dvd navigation error structure" message. I have on the burnt dvd VIDEO_TS folder but no AUDIO_TS folder, on my origanal Silence of the lambs disk it has both but there is nothing in the audio. should I have copied a blank AUDIO_TS folder to my back up? any help on this would be greatly appreciated, this is my first attempt at backing up my libary. I am using a Matsushita (panasonic) LF-d311sc 1x burner & using bulkpaq 2x media on W2K.
