Perhaps another option would be to open those DTS hd ma tracks in audacity and save them as LPCM?
Bingo. This is exactly what I would do. No loss in quality, more universal support.
As a matter of fact, that’s exactly what I did to make the lossless files playable on my Apple TV. I demuxed the DTS, opened in Audacity, converted to PCM. Then I compressed to Apple Lossless to save more space and muxed them back into an MP4 container.
