I would like to be able to work with and utilize m4v video files, but I am having trouble converting them accurately to other formats. Programs like DRM Buster or Format Factory get around the DRM protection by playing back the video and recording the playback on your PC. I have not had great success with this method. The resulting mpg or avi video is often choppy, and the audio and video is usually out of sync. Also, if you happen to move the cursor or open another program while the file conversion is in process, this will be incorporated into the video. There has to be a more direct way to convert m4v to mpg or avi, doesn't there? Anyone have any ideas on this matter?
