Comment (by pbennett):

 MythTV is finding the wrong framerate for the video, it thinks it is 50fps
 interlaced, which means 100 fields per second. It may be a consequence of
 some MythTV customizations of ffmpeg, because ffprobe gives the correct
 25fps but mythffprobe gives 50fps.

 Presumably the 50 it is picking up is the number of fields per second
 rather than frames per second.

 Assuming that interlaced content is always 25fps or 30fps, I can make a
 simple change to correct the double rate check by assuming that anything
 that has interlaced content with higher than 33 fps is getting a doubled
 value, and adjusting accordingly.
