It seems a whole section of my 350+ movies in my iTunes have all of a sudden stopped playing back. These are movies that played back perfectly just a few days ago but now only display a black screen with the timeline ticking away as if it was playing. All these movies were ripped from DVD's and converted using Handbrake. Has this happened to anyone else? I think its some type of file corruption but I can't imagine what caused it. What makes it strange is that it only happened to a section of movies and not one common trait can be found among them. I've done a bit of googling and mroogling and haven't been able to find a solution let alone another user have the same problem. Any ideas? I have all the video_ts folders backed up so I just need to encode them again, but I would like to prevent this from happening again. Thanks for any replies.
