I substitued 'mpeg4' with 'mjpeg' and successfully transcoded the
sample BBC 1080i clip I dowloaded from here
(I presume it's the same one mentioned by the OP, since it also
features David Attenborough and a storm)
into something that plays full speed with picture and sound on my AMD
64 3000. However I have much still to understand. For one thing the
transcoded clip is smaller than the original (40MB vs 50MB), so either
I've lost some of the quality or I didn't get to the end of the clip,
and I have yet to repeat the success with any of the clips that I've
captured off my Nova-T card.
On I go.
Thanks for the help.
