Convert the .mkv files to a format my tv supports

[Goldenbrown]

Ive been trying this for a while now.. and so far all unsuccessful, so i hope someone can guide me.

Problem: I have a fair few BD in .mkv format that when i took my pc off the tv, the tv does not support the audio file. Now the 2 programs i have been trying (and failing) are 'Xilisoft Video Converter' & 'Next Video Converter 3.62'. the issus is, i cannot work out how to convert the .mkv files to a format my tv supports but keep the quality of the BD. I am at a loss, this is the only file my tv doesn't seem to play fair with, which is typical as most BD 720/1080's are in .mkv format these days.
Please, if anyone can possible point me in the right direction i would be greatly appreciative.

In order for someone to provide sensible help post a MediaInfo report on the file/s in question. Also to avoid playing 20 questions with lots of posts reveal some details of your TV brand and model. The more information the better!

DL MediaInfo. Drop your video into it and post the 'Tree view' results here.
