Ok I managed to get it working. Since I do not have a BD drive I had to get the movie from 'elsewhere'. My first video file had messed up FPS setting which is why it was failing with tsmuxer. I found another one which reported it correctly as 23.976fps.

Once question, when I view the codec info in VLC, is it supposed to report the track as DTS-HD MA? It simply says DTS audio on mine. I didn't check box marked 'downconvert to DTS'.

You'd have to have the proper CODECs installed to decode the DTS-HD MA audio, my understanding is if the transport cannot handle DTS-HD MA, it will default to decoding the DTS core (lossy) stream that's contained within the DTS-HD MA track. In that case, you're still hearing the original mix, it's just not lossless.

If anyone notices any discrepancies with sync and the DTS-HD MA track, please update the thread. I was only able to test using 5.1 PCM because I only have access to free and open source tools. I'm confident that the DTS-HD MA track that borisanddoris was able to encode is identical, but I won't be able to test it out until I finish the download and perform the same steps you all are taking ;)
