Having an issue backing up a movie. Ran Dvd Decrypter, and attempted to run DVD shrink. Shrink came back with an error message "Invalid data file...". Ran VobBlanker and several errors showed up. I took screen shots but I'm not sure how to post them here. First error stated something to the effect "detected 2 cells with pointers mismatch...", then the next error "detected ini\end cell pointers out of range in titles domain...", was able to move forward and process but when it is almost complete, ~99%, I get the error "error opening input vob:\fearless\video_ts\vts_02_01.vob". The vob process stops and trying to run dvd shrink on the files that were produced comes up with an error as well.
Perhaps Decrypter alone can't handle it. You could download Anydvd, run it in the background and try re-ripping with decrypter. EDIT:see 'alkohol's' post here: http://forums.afterdawn.com/thread_view.cfm/415748 but still run 'anydvd', it works.
