Copying the mp4 to a new mp4 with ffmpeg - file still will not play.
ffmpeg -i rcarballo.mp4 -acodec copy -vcodec copy rcarballo_copy.mp4
Copying the file to an mkv with mkvmerge - file plays OK.
mkvmerge -o rcarballo_mkv.mkv rcarballo.mp4
Copy the mkv file back to an mp4 with ffmpeg - file plays OK.
ffmpeg -i rcarballo_mkv.mkv -acodec copy -vcodec copy rcarballo_mkv_mp4.mp4

This seems to be just an issue with "Brorsoft DVD Ripper". Unless it becomes more of a widespread problem, I am inclined to close this without looking at it further. Those who want to use Brorsoft DVD Ripper can run mkvmerge afterwards as described above to fix the file. Alternatively do the DVD ripping with HandBrake which comes for free with Linux and Windows versions. I use that extensively to transcode recordings and well as DVDs to x264 and all recordings play perfectly with MythTV including on Raspberry Pi.
