The lavc float to fraction code strikes again!

mplayer doesn't have the exact correct framesrates for mpeg files (too few
significant digits), and then it (stupidly) converts frame-rates to a 32-bit
float, which is then converted back into a (different) fraction by code in
lavc.  This can't be fixed, as certain people don't believe it happens.
