Hi, I need some help to convert .dv and .avi files to ipod touch compatible files using handbrake. When I try to choose either file type as the source file it just says 'no valid title found'. The .dv file is a clip shot with my video camera and imported onto my mac using imovie, then saved as separate full quality file, in order to have a separate file that is not sitting in imovie. The .avi file is a downloaded movie. Both movies play fine in quicktime player and VLC player. The Handbrake program does work as I have successfully converted a file ripped from a dvd using mactheripper. I am surprised that I can't get it to work, as other threads on this forum recommends handbrake as the best software for video conversions for ipod, so any help will be gratefully received. Thanks.
