I decided to rip my tv show dvds and have available on a DLNA server and then I bought the BDP 5200/12 and thought I would be able to play all my ripped files. I chose to rip it in MKV so I could have subtitle and multiple audio tracks. It plays for half a second and then stops.

here is some kind of a transcript from mediainfo
