I do the same as above, however to get the audio working in MythTV apply this patch (this is against trunk, but should work for fixes), this is due to tsMuxer not changing the codec ID correctly.
The patch just tells it to treat it the same as DTS for the moment, as there is no decoder for HDMV DTS.

One thing that annoys me at the moment is no subtitle support, which is annoying for foreign movies...
