Transcode every MKV-File

Hello, I bought Serviio today and I try to edit one profile for my LG BP 730 blue ray player. This player plays the most of my mkv's but sometimes it stucks... so I tried to edit a existing profile in Serviio. All I want is, that serviio transcode every mkv with a max bitrate like 10mbit/s with best audio in 5.1 and in the correct language or with all of them. My profile works now (the BP 730 plays the file fluid) with lots of mkv's but some of them will not transcoded while playing them. Often I get the wrong language and only in stereo. Can anyone help me?
