Since it is unclear to me if you have a problem that is both reproducible with
the original and the new file or only the new file:
Does the original file play fine with ffplay?
with mplayer? With mplayer -speed 0.3?
(=Is it a performance problem you see?)
What about ffmpeg -i source.mov -s 480x260 out.avi?
Or ffmpeg -i source.mov -s 480x260 -vcodec mpeg4 -strict experimental -acodec
Does the resulting file play ok?
