If you do not change your posts about MKV & H.264 & DSM-510, I'll report you to moderators as your posts looks like advertisement for TVersity all over the forum.
Please, try to understand that product you are pointing to IS NOT always the solution. What if I my customers want to watch MKV videos directly from some UPnP NAS device? Telling them they need to do conversion from MKV to VOB or to stream trough TVersity is not near good solution. They want (yes, they asked me for this) firmware with better support for MKV files.
Now, the below lines should be seen by D-Link sales managers:
You sent us price lists with promotion prices for DSM-510 in Adria region before 2 months I believe. You are underlining DSM-510 DivX support! Did you know that most (if not all of them) customers here watch DivX movies with subtitles. And how good is DivX subtitle support in DSM-510? The answer is one question: Could it bee worsen!?
Now, you could tell me that D-Link has more expensive devices with better support for subtitles. Yes, and I can tell you that PM for WD in my company has device which costs far less then DSM-510 on stock with far better support for DivX subs and (watch this) excellent MKV support! Of course, WDTV is not networked device - D-Link DSM-510 is networked device with no support for the MOST popular High Def format on the planet.
