Hi, i have weird problem. I have some mkv files that are normally loaded via O!Play but video is not displayed at all. Picture stays black, subtitles are shown and audio is played. I tried to find out what could be the problem but the only think i found is that files that were created using mkvtoolnix 4.3.0 are all affected. Anyone else has the same problem? And if so, how to fix it?

The problem is "header removal compression" in the new versions of mkvtoolnix.

Asus needs to release a compatible fix for this.

In the mean time you can either remux the file without compression with mkvtoolnix or try this easier "one click" method found here:

I also have the same problem... And it has nothing to do with "invalid file" as Poker thread is all about..

I can play the .mkv just fine. Sound is good, but there is no picture..

I have tryed Pokers idea, but it does not help...

Is there anyone with a better solution...??

Thanks

This Asus "media center" is the worst peace os crap i have ever bought..

No support from Asus what-so-ever..
No firmware updates that do anything good..

Im looking forward to getting my popcorn hour...

Remuxing the mkv files in mkvmerge (without header compression) does make the videos playable. Give it a try!

grab mkvmerge here:http://www.bunkus.org/videotools/mkvtoolnix/. Here's a site that describes the problem and how to fix it using mkvmerge: http://www.mediasmartserver.net/2010/08/09/mkv-mania-header-compression-and-the-side-effects/. In a nutshell: if you are using mkvmerge versions 4.0 and up, you need to select 'None' for compression - do that for both audio and video streams. Then remux. It sounds complicated but it's just takes a few mouse clicks and the program will do the rest. On my machine it takes no more than 2 min to remux a 8gb movie.

It's not just the O!Play that has problems with the header compression, but also some software players can't handle it. I just removed the new version and installed an old version - no point in having features that will never be used.

I am curious what software players have problem with header compression? Header compression has been part of the MKV specifications since the beginning. If there really are software players out there that have issues with Header Compression, I gaurentee you they have fixes for the problem out by now. Why is it taking Asus so long to fix this in their product? Who knows. But I can tell you I will not be picking up any more Asus Media Streaming products in the future unless they fix this bug in their existing product line.
