It seems the number one issue in this forum these days is that of mkv playback. This is also very much an issue for me, and I have involved myself in some of the posts. Well, I've got some interesting news. Here's the story, start to finish.
I only use this device as a Media Center Extender. I was of course very disappointed when firmware 1.02 came out, and mkvs still did not work in MCE mode. I repeatedly complained (both on this forum, and on the phone), and was always told that there is a limitation in the Media Center Extender specs that prevents mkvs from working. Frankly, I never really believed this because there's no reason that mp4 files would work (which they do) and not mkvs, since both containers typically contain the same audio/video streams and neither is natively supported by Vista.
When Windows 7 beta (and then RC) was released, I installed each on my computer and did some testing. Of course, I was sorely disappointed that mkv is still not natively supported by Windows. But, we mkv users now have a White Knight to help fight our battles: DivX. Their new "DivX Plus" setup uses mkv as a container. Now, with Vista, when you install DivX it installs an mkv splitter, and H.264 + AAC codecs. Windows 7 is a different story, however, because it already has H.264 + AAC codecs (and because it uses Media Foundation instead of DirectShow, which I won't get into).
So when the Windows 7 RC came out, DivX released a "Windows 7 technical preview" at labs.divx.com. Install it, they said, and you will be able to play mkv files in Windows Media Player, Windows Media Center, and - get this - Media Center Extenders.
The forum there immediately began filling up with success/failure stories from XboX 360 users, which is clearly the most common Extender. I tried it myself with the DSM-750, and one of two things happened - either the video would play but it was clearly being transcoded (which is an issue that Windows 7 is having with other file types, including avi), or it would play audio with a black screen. I posted a few times on their forum, and it was eventually determined that D-Link needs to fix something on their end to get this working.
I spent awhile on the phone with D-Link - first with a Level 1 support agent, then with a Level 2 support agent, then a Level 3 product specialist. Finally what I was told is thatthey are aware of this problem and will be addressing it in their next firmware update.
So, the obvious questions:
-When does this firmware update come out?
-Will it make mkv files work with Vista in Media Center Extender mode?
