Issue: cannot play certain mkv files on Samsung C-series

I think Serviio is awesome. I have had very few issues with it and works well with my setup. Recently I have found certain mkv files do not work with my setup. My setup:
-Windows XP
-Samsung TV UN46C series

Using MediaInfo I was able to notice that files encoded with Handbrake work, but files encoded with mkvmerge v4.7.0 do not work on my Samsung UN46C...

Here's the output from MediaInfo:


Working mkv:

  Code:

Complete name                            : C:\Documents and Settings\All Users\Documents\My Videos\<snip>\Star Wars The Clone Wars s02e01-e02 720p-HDTV.mkv
Format                                   : Matroska
Format version                           : Version 2
File size                                : 600 MiB
Duration                                 : 43mn 21s
Overall bit rate                         : 1 936 Kbps
Writing application                      : HandBrake 0.9.5
Writing library                          : libmkv 0.6.4.1

Non-working mkv:

  Code:

Complete name                            : C:\Documents and Settings\All Users\Documents\My Videos\<snip>\Star Wars The Clone Wars s02e03 720p-HDTV.mkv
Format                                   : Matroska

Overall bit rate                         : 1 743 Kbps
Encoded date                             : UTC 2011-06-07 20:14:33
Writing application                      : mkvmerge v4.7.0 ('Just Like You Imagined') gemaakt op Apr 21 2011 01:13:14
Writing library                          : libebml v1.2.0 + libmatroska v1.1.0

So I did some reading and re-encoded an offending file with HandBrake and it worked. The question I have is, why?

Output from ffmpeg:

Can anyone help me out why these mkv files do not play?

I am going to be vague and possibly wrong if my memory fails me. The MKV format and ffmpeg do not always get along. MKV is a great container for video and audio however ffmpeg is a little behind with bugs if memory serves. Also if I remember right it is the audio track that causes ffmpeg to not play the video. That being said if you have a method that works do not deviate from it. If you find more files try to remember how you made them and if you deviated from your working method. ffmpeg will eventually catch up.

I always use a .mkv with no issues... anymore. Find what works for you.

FFmpeg doesn't come into play for the Samsung profile really, it plays MKV natively. It's therefore something the TV's deoder doesn't like, might be compressed headers or similar.
