Why do you think it is VFR? Is it because it doesn't play on the PS3,
and mediainfo says it is VFR?

That is not necessarily conclusive - it could not play for a number of
reasons, and mediainfo can easily be wrong - I've never ever seen an
ffmpeg dev remotely interested in what mediainfo has to say about a
file :)

What does *ffmpeg* say about it?
