Hello.
I have some MKV files that I'd like to watch via an external hard drive. I tried to play the files, the video is fine but I'm not getting any audio or subtitles. When I play these files on my PC all is fine. I am able to hear the audio and select the subtitles.

I loaded these files into an mkv demuxer, and it is reporting that the files have no individual streams whatsoever. Can anyone tell me what may have gone wrong with these files? Would there be a way to make everything work correctly so I can watch it via my external hard drive?

Thanks.
