I use Samsung DLNA... but i don't know Mezzmo.
I see several problem with Bluray due to data bitrate.. encode method... but DVD it's hard to believe.
The problem seem be Mezzmo but it's could be the DLNA also.
I don't even see mkv in the supported format on Mezzmo website.

File from MakeMKV could not be optimal for streaming.. because he create the video as is.
Variant bitrate... data allignment... ect..
If you're able to read the file with other player like vlc or mplayer... to problem aren't the file.
(but this doesn't mean another program could have trouble to read it).
1.this could be stupid as.. Mezzmo doesn't have streaming index.. so after 20minutes.. he need to re-read the file
2.also... since DLNA aren't the same with all manifacturer... the issue could come from Samsung DLNA...
This hard seeing which one: the software or the DLNA cause problem.
If it's always crash on the same place, this mean software or DLNA.
If you can't pass over this 20 minutes glitch in fast forward, this mean software.
Else.. this could be one or the other.
I recommend to reencode with Handbrake.. this fix the bitrate and it's optimized for streaming.
Everytime, Handbrake make it's works great.
With a Bluray I always reencode using Handbrake (Smaller file optimized for streaming) or Divx/Xvid also works great.
I used Windows 7 media center and a Samsung DLNA, without reencoding.. I see issue with:
-"Toy Story 3"... I see something like after image blinking...
-"Alice in wonderland (2010)" encode glitch...
Since that...
I reencode everything.
Your problem could be something similar. I'm not sure who is the cupid... the AVC format, the software or the DLNA.
