Current code will call avpriv_set_pts_info() for each video frame, possibly setting a different timebase if the stream framerate changes. This violates API conventions, as the timebase is supposed to stay constant after stream creation. Change the demuxer to set a single timebase that is fine enough to handle all supported DV framerates. The seek tests change slightly because the new timebase is more granular.
