Thanks Rafael. Should I transcode the 720p50 to a PAL upper field first? When I made a test dvd from an upper field sequence, the720p50 footage gave judder on the TV, the other footage moved smooth as butter. I can use a high end system for the rendering and transcoding of files. We just had to edit it on a medium performance machine due to budget constraints.
Mark.
