Please add support for PGS subtitles (and SUB/IDX, VOBSUB) for the Blu Ray rips into MKV format.  I am hearing impaired and rely on subtitles to watch my videos.  The subtitles for DVD rips into MKV work great, but I cannot view those from my Blu Ray MKV collection.  I am using MakeMKV for my conversion to Blu Ray and the subtitles show up fine on my computer, I had the suspicion that the issue was with the WDTVLive.  Customer support has since confirmed this issue.  Please include this support!
