WD TV Live Firmware Pre-release Update (3/17/10)

I have that firmware loaded right now and I can not get subtitle to work at all with BluRay content.  DVD content works just fine.

I have tired the following.

Adding the .srt file with the name of the movie file (MyMovie.mkv and MyMovie.srt)

Addind .idx and .sub files, again with the same naming convention as above.

remuxing them back in using TSMuxer.

I can not get subtitles for BluRay content to work no matter what I do.  Is there another way to get these to work?
