 Videos created with Brosoft DVD Ripper do not play on Raspberry Pi.
 They remain on "Please wait" indefinitely. On amd64 frontend they play
 fine.

 Log shows: \\
 Many of these messages: \\
 `Waited 29807ms for video buffers LLAAAAAAAPPP` \\
 Then many of these messages: \\
 `Waited 100ms for decoder to pause` \\
 Then these messages continue until you kill the frontend:\\
 `Waited 10ms for decoder lock` \\

 Investigation:\\
 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`\\
