Dean,

The files you are seeing are correct.  The live transcode creates multiple
small chunk files of the recordings.  Then they are added to a .m3u8
playlist, which is streamed to MythTV for Android, or the JWPlayer, etc.

When was the last time that you updated the backend.  There was an issue a
few months back where HLS was starting, but no stream was coming out.  It
is fixed now in the source.  If you haven't updated in a while, then I
believe this is the issue you are seeing.
