MKV, 1:37 long, audio always comes out 44 mins only..

[TheGlow]

I had some anime from awhile ago, 24 episodes and 2 movies.
I just converted all of them with xvid4psp for my xbox 360 and all was smooth. except the last one.
This movie is 1 hour, 37 mins. I dont understand, I run xvid4psp, the audio is off since its not starting properly and its only 44 mins long. I used mkvextractgui and it only spits out a 44min video. I used virtualdubmod to take a look, that also said the audios only 44 mins. this applies to both the english and japanese track. If I play the original mkv, both channels work fine
I tried mkvmerge to maybe remove the english channel and rebuild the mkv. now it magically cuts the video to 44 mins as well, namely the last 44 mins of the video.
any idea what could be going on?

That all seems to point to a break in the audio file at 44 min. You could try to demux or extract the audio out and see if you can get it all, but you may still end up with a 44 minute audio file. Software players like VLC can sometimes skip over a break, but encoders need a 100% error free file most of the time.

Try AviDemux.
If it can play past the 44 minutes, do "save as" (video and audio just "copy").
This often makes a usable file from a damaged one.
You might have visible or audible glitches at the break, you can edit those out if necessary.

Avidemux says its a 44 min video as well, and just the last 44.
Im not that experienced with editing and conversion but everything else ive tried to use to demux results in the last 44 mins of the audio.
Media player classic is fine. Im baffled
And this MediaInfo app also says 44min, 4 secs...

Are you saying MPC plays the full video length? What is the filesize of the video (i.e. does it look right compared to the other episodes) ?

Try using GDSMux (comes with haali media splitter) to repackage the mkv

Yea, MPC plays the video perfectly fine, full length.
Correction, it used to... It worked fine last night, now it doesnt. only change I can think of is I installed the haali media splitter just now to try GDSMux.
well, prior to that yes MPC played it fine, full length. Could switch between both audio channels perfectly fine. File size was 702, matched the movies part 1 of 701mb. And the whole set was encoded by the same group so I dont see how they might have decided to change it up at the end. Now I have to figure out whats changed.

I just tried it in VLC, interestingly it reports that its 1:37:10 long like it should, when you hit play, it jumps automatically to the 53min mark, leaving 44mins..
I noticed when installing the haali media splitter, there was an option"disable mpc internal matroska splitter"
how can I reenable that if thats what I think is the problem with MPC?

Ok, Wow. I sort of figured this out. Ive never seen this before.
file names were x-themovie-part1.mkv and x-themovie-part2.mkv
somehow if both are in the same folder, if you open either one in MPC itll show the full movie at 1 hour, 37 mins, 10 secs.
If I move either one out, then it only plays that ones half, part 1 53:05 and part 2 44:04... Even If I rename the files, they somehow magically join while in the same folder.
xvid4psp is where I got confused because it went ahead and made part1 1:37 long but with only the audio for the 53 mins.
Is this some kind of normal practice because I didnt catch onto this until I opened the part2 subtitles and noticed the first line said to play at 53 mins. i thought it should restart the timers to 00 since its a new file, and got to wondering how it could know it starts at 53. Thats why the movies stopped working for me, because i moved part1 to a completed folder...
Awkward. Im just gonna keep em separate, convert them and leave it as is. But I found that very very weird...
