AFAICT this WLSDT is not broadcasting broken streams, they are just using
an encoding extension we don't support very well. These streams do in fact
play on powerful MythTV machines. I believe they are broadcasting about 40
fps on a 60fps stream and marking some of the frames as repeatable, but I
haven't added the debugging statements to MythTV to confirm this. If true,
MythTV doesn't know what is going on and so the only way it adjusts is with
the A/V sync code. This works, but is CPU intensive.
