Can't listen audio track from separate file
 

I have film in *.mkv file with built-in audio track and I have separate file *.dts with another audio track. In BSPlayer I can only select built-in track, but can't select track from *.dts file. Media Player Classic can work with them all. I have ffdshow, ac3codec, haali splitter installed and latest BSPlayer version.

What can you advice to me?

If you have associated the DTS files with BSPlayer from preferences menu, then you should be able to use the "open audio file" from main menu. This way, you can view the video file with the external audio track. In here is working like a charm.
