The video part of that report is identical to the video part of other MKV files I have played successfully
except for the "Muxing mode" field.
And the player's manual says it can handle AAC audio.
So any idea why this won't play?
I think your issue is with the header compression (Muxing Mode="Header stripping").
I have an S570 and have enjoyed it so far with MKV movies but I have run into MKV glitches that I was able to iron-out.
1) If you try to make your own MKV files, FORMAT=AVC and PROFILE=HIGH@L4.1 is pretty much a given and the player will not play if FORMAT/PROFILE=Main@main or Custom@custom.
2) My S570 won't play the MKV if it has PROFILE=HIGH@L5.1 I think the symptom is not just a "corrupted file/cannot play" message but the player is hang and shutdown after a minute. You can use TS_MUXER to extract the video stream and have it re-labelled as HIGH@4.1 (no video conversion necessary). Most of the time, this re-labelling will work but sometimes there is horrible visual digital artifacts and video conversion is required. Use MKVToolNix to mux that new video stream back into a new MKV file.
3) My S570 won't play an MKV with PROFILE=HIGH@L4.1 if ReFrames are as high as 16frames. I think ReFrames=8frames is the limit for playability. Video conversion is required to reduce the ReFrames of a video stream.
4) My S570 has problems with an MKV if there is any compression in the headers (labelled Header Stripping if there is compression). Use MKVToolNix to mux a new MKV with no compression on the video, audio, and subtitle text streams (no video conversion necessary).
These fixes have solved most of my issues but there are still MKV files that I cannot play for some reason. BTW, when I refer to "play" I mean playing from a BD-R bluray disk or a USB 4gb FAT thumb drive (not the DLNA network).
