Right now I've been ripping some of my bluray dvds, and I usually just keep the "main" m2ts file. The problem is, though, that when I play a m2ts file that has DTS audio in powerdvd or PVRX2, the audio is missing. I know it's present, though, because mpc-hc plays back the audio fine. As well, when I play the blu-ray as a disc using powerdvd or if I mount an iso of the DVD, the audio plays back fine. Also, I've tried demuxing the m2ts file, and powerdvd plays back audio-only .dts file fine. However, when I remux it, the same problem occurs.

Does anyone know what I need to do so that the dts audio is recognized?
