I seem to be making some progress with these parameters:
-vcodec dvvideo -s 720x576 -vtag dvsd -pix_fmt yuv420p -r 25 -f avi -acodec
pcm_s16le -ac 2 -ar 4
However, when playing back in WMP (which finally works) the 16x9 image is
squeezed into a 4x3 frame.
I need to make my parameters flexible so they can take either 4x3 or 16x9
and keep the aspect ratio on the output files, even if it's 16x9 HD
downscaled to PAL DV.
