So what about MPEG files created by IVTV (is there some better way I
should identify the format?)?  Do you know where the value comes from
with those?

If it's extrapolated, it's a pretty naive extrapolation when it shows
total length less than the current position.

I should add that the the value usually matches the actual run time
within a second.
