Your XML says <producer in="81.0" novdpau="1" out="162.0"> But 162 @ 25 fps is 6.48s. How can you expect it to to "play" longer than the end of the file?

If one wants to exceed the length of a clip it must do so explicitly by adding the "length" attribute to that producer element: length="163". Then it exhibits this behavior you expect. I do not feel the need to make any further changes. -- +-DRD-+ ------------------------------------------------------------------------------ WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.
