#5940 closed patch (fixed)

Allows MPEG TS parser to properly parse HD audio tracks

Description

This patch adds proper parsing to mpegts.c/h for HD audio formats. There are some problems with playback of DTS-HD MA audio tracks, but I am working on getting those looked at upstream. Since Myth uses its own version of mpegts.c/h, though, it seemed safe to apply these so that all of the tracks are visible in m2ts files. DTS-HD MA currently results in slow playback and no audio, but nothing catastrophic. The other audio formats parsed by this play properly.
