Actually, the first thing I did was load it up into mkvmerge last night so I could remove all but one audio track to easily stream it across my wireless network. (I still keep an original around because I like the commentaries, etc) While doing so, I had the very first 5.1 track selected and all others unchecked and started the process. I noticed that the 'time remaining' kept going up about 1/3 of the way through the process and then I saw the error log window. It kept repeating at a very fast rate:

"Warning: DTS_Header problem: invalid source PCM resolution"

I let it go and it finally errored out after a few more minutes, unable to continue.

So, I unchecked the 5.1 DTS track and went for Track 5, the 93 LD AC3 version because I really wanted to watch it last night. Well, it coughed up about 5-6 timecode errors during the re-muxing but said that it was able to recover each one, so I let it go.

This is just one of them:

"(filename):Error in the Matroska file structure at position 7508142148. Resyncing to the next level 1 element.
The last timecode processed before the error was encountered was 00:45:37.9020000000 .
Resyncing successfaul at position 7517875330"

I went into our living room to watch on the big screen and at the point ray_afraid mentions above, the screen just blacks out for a moment - then it continues on. I just thought it was my media box having being glitchy (it's been known to be at times.)

But after I read ray's post, I remembered something happening at that point last night and loaded it up into VLC here on the computer to verify. At 45:37, I got the black screen at the same point but then....VLC crashed! Unable to continue playing with just a basic APPCRASH error message.

Maybe we should hold off on putting this out publicly for a moment until the bugs are verified and worked out?
