FWIW, the ticket is wrong about, "Running a mythcommflag --rebuild on
the offending file will resolve the improper length, however it would
take significant work to manually rebuild all existing recordings in the
library impacted by this problem."
I have run --rebuild against all of nearly 2000 recordings and it took
only a few seconds of my time (and a day or 2 of background computer
time). Just set up a script to loop over all the files in the
recordings directories and queue a rebuild for each (and, for bonus
points, have it skip any "new since upgrade" recordings).
