Well tsmuxer won't even take a 44.1khz file into it.

I typically mix everything into either Blu-ray or M2TS streams for the Oppo. It works with MKV, but won't do lossless tracks with MKVs, unless it's PCM.

Hmmmm that doesn't surprise, thanks borisanddoris

My Oppo BDP-80 will play BD-Rs containing MKVs with 44.1kHz LPCM 2.0, but it has a lot of bugs, like ignoring the chapter stops, and deciding to jump back to the very beginning if I try to rewind, and then stopping playback if I try to fast forward to the place where I left off (so I'm screwed unless I want to watch the whole thing again). My Popcorn Hour does a pretty good job with MKVs, but its kind of a pain to use in my setup so I prefer to mux to BDMV and playback in my PS3 or Oppo.

and kind of surprised the Oppo gets that far, thanks BusterD
