Comment (by Timothy Pearson <kb9vqf@…>):

 This hit me as well when I upgraded my old 0.24 installation to 0.27.
 Many (but not all) of my H264 recordings became unwatchable; the system
 would sit for 10 seconds at the "Please Wait" screen while spewing "Taking
 too long to be allowed to read" on the terminal.  Needless to say the WAF
 dropped to zero at this point. ;-)

 The workaround mentioned in the linked thread (mythfrontend -O FFMPEGTS=1)
 restored playback functionality.  Further analysis showed the failing
 recordings to contain multiple resolution changes including one near the
 end of the file.  mythffplay and ffplay think the failing files are only a
 second long when in fact they are nearer to 1-2 hours in length, yet both
 play the file perfectly.  Perhaps this is a clue?

 If anyone wants to investigate I think I have a reliable method for
 producing these unplayable files.  I can try it with Big Buck Bunny or
 similar and post the resulting file for analysis if desired.
