I managed to rip part of a dvd with a pioneer dvd burner, saved it as mpeg and imported it to my studio 8 and studio 9 (tried both) The movie scenes play fine in the preview window but when I move them to the storyboard, the audio jerks in places. Any idea wether this is a problem with studio or the program I ripped the video with (AliveDVD)

Thanks for any help, I'm very new to this.
