Sony media player help

I have a n100 Sony media player and can’t play mkv files. I want to keep the picture quality and sound. Is there a download that I can download it to have it play MKV files.
Thank You.

That sounds typical of Sony…No one has told them that MKV has been invented!

Use Mkv2Vob to quickly remux the file into a compatible container..
