I have over 200 full length movies and I have put them onto my iPod touch. They have played perfectly. When I put them on my iPad from iTunes, they sync fine. ( No error messages saying the file is incompatible. ) Then when I start watching them in the videos app the picture is stunning, but there is absolutely no sound. Any help you could give? If it worked on iPod shouldnt it work on iPad, particularly since it one of the more commonly used file types?
