After DVD movie is converted to MP4 File(.mp4), I transfered it to i-Tunes. All I see is a white window with movie's name under it, the one I typed. On playing I can hear the sound but there is no picture in itunes. This conversion sucsessfully worked in the past on my ipod. I tried another software and MP4 files show clearly in itunes with logo of Disney etc. and play well in itunes window. Since I have purchased DVD mobile, I would like this to work. Any help will be appreciated.
