Audios and subs streams in DVBviewer

Hi!

 

I9;m using a HTPC software for watching DVB-S, DVB-T ; matroskas, AVIs, for listening to MP3...  It's called DVBviewer and it's fine. ; But the only problem is how to choose audio and subtitle from my remote while playing MKV (like I do on all the other formats). I have to set that from the keyboard and it's very unconfortable.

 

Is there any option or plugin to become these streams visible for DVBviewer  ??

 

Thanks.
