Thanks for the update. It is interesting that they somehow think it is a
silicondust problem, but anybody using mpeg2 would be affected. With
MythTV, we are able to use ffmpeg software decoding (if we set an
appropriate number of threads) without any adverse effect. I notice that
others report that kodi with software decoding is unacceptable on the
shield. They must not be using ffmpeg for software decoding, or maybe
are only using one thread.
