+    <p>As the matroska container is being widely used for content distribution

+      of requests on how to be able to convert MKV files into VCD/S-VCD or DVD 
+      files. This is generally speaking not an easy task, as the MKV container 
+      is the most powerful multimedia container today, offering support for a 
+      huge variety of different audio, video and subtitles formats in a single 
+      MKV file. As VCDs are limited to MPEG1 compression only, and S-VCDs and 
+      DVDs require MPEG2 compression at least for the video tracks, this conversion 
+      is only possible with a MPEG encoder.</p>
+    <p>While there are many MPEG encoders out there, the most well known probably being TMPG Encoder, most of them do not offer a suitable interface to read in MKV files, but are limited to AVI files. The tool being used here, DVD Santa 4.0, is however offering the possibility to read all kinds of video and audio files in, by using a powerful DirectShow reader plugin. DirectShow is a part of every modern Windows OS, and the underlying platform for video and audio playback in Windows Mediaplayer. In other words, the creators of DVD Santa have found a way to read all media files into their encoder, if they will play in Windows Mediaplayer. If you are being familiar with matroska already, and have read our Guide section a little bit, you may know already that we are offering a splitter filter for Microsoft DirectShow, allowing playback of matroska video and audio files (.mkv/.mka) in Windows Mediaplayer, as well as any other DirectShow based player (see our Windows Playback Gu!
 ide section to learn which alternative players we are recommending). As the success of the conversion process is depending on playability of the MKV files in WMP, let do this first :</p>

 <h3>Step 1 : Installation of the matroska playback pack, to enable MKV/MKA playback in WMP</h3>
 <p>Goto <a href="http://packs.matroska.org/">http://packs.matroska.org</a> and download and install one of the matroska playback packs. If you are having any video codec pack installed already, you may try the lite version of the matroska pack first, to avoid conflicts (unlikely, but possible). Only if your MKV file does still not play after installation of the lite pack, or if you dont have any other codec packs installed, go for the full pack instead. </p>
 <p>Now open an Explorer window (not Internet Explorer, just Explorer) and search for the file 'mplayer2.exe' on your Windows drive (normally C:\\). By double clicking on the .exe file, you will start a very old, stable and lean version of Windows Mediaplayer, WMP 6.4. Most Pro's prefer to use this older version of Microsoft's player, as the more modern versions are typically overloaded with a lot of features, and are causing conflicts and other problems in many cases, especially with multimedia software that has not been developed by Microsoft themselves ;) ....</p>
