I have been trying to back up my copy of passion of the christ. I have never had a problem with any movie doing this. I use anydvd and clonedvd2 both updated. it burns great, but when i play it back there is no sound. so I put my copy in to make sure the sound was working properly on it, and as long as anydvd was on, there was no sound. I would really love to back this up as it seems to be wearing out.anyone have any suggestions???
