Probably a bad idea, since those who use "cp" instead of "cp -p" to copy
a file will reset that date.
Since this is such a specialized case (possibly-identical results from
manual runs of ffmpeg while testing something), I wonder if there might
be some other workaround that can be used in that workflow, rather than
by changing mythtv. ffmpeg and avconv both have the -metadata flag, for
example; perhaps that can be used to embed unique metadata at the start
of the file in a place that the hash will see. The easiest metadata to
use is probably seconds or nanoseconds since the epoch.
