Still having problems with my BD-D5700

If I convert the VOB files to MKV I have no problems at all it streams without any problems. In that respect the notion of having network problems is out of the question. Is there any profile more direct for my Blue Ray player that transcode and play VOB file format? because I still get the CODEC not supported.

I know that my BR player does not support VOB format but does support MKV.
Also how do I play the movies that shows the Play / Setup/ etc on the tv. If I press Play on the remote control it does not work I have to go to the next file in order to get the movie play.
Anyway my main issue is to get the VOB to play without any issues.

Thank you very much for your help.
