This looks like a DRM'd file with a scrambled video track

Could you please share the verbose logs?

Tools->messages, set verbosity to 2 then start the video (from stopped mode not paused).

I'll check that. Thanks for reporting.

MKV theoretically allow that but I'm quite sure that VLC doesn't support it.

VLC use the name inside the file; so unless you remux your file (with mkvmerge for example), you can't change that.

I'm looking at it but the file doesn't have obvious problems... the demux may not be the only responsible. I'd tend to also blame the audio core.

I already started investigating this issue... it's a timing issue either in libvlc or mkv demux. It seems to be related to 5.1 AC3.
Sadly I still have to figure out a way to fix it.

Or at least a part of the file. The first 10 or 20 MB should be enough if the crash happens at 1:30

If you just reinstalled windows you may try to update your video drivers and DirectX

Could you please upload a sample on http://streams.videolan.org/upload/? The first few MBs should be enough. According to your logs VLC doesn't recognize your file as a MKV...

Could you please share the logs? Tools->Messages set verbosity to 2 then start playback.

To fix many mkv problems the seek precision has been improved but it is heavier on the CPU. You can also try to enable GPU decoding, save and restart vlc.

if i untick accelerated video output (overlay) then save in vlc. i still have alot pixels (image above).

You have to disable GPU decoding not overlay. It's in the codec thumbnail in Tools->preferences then save and restart vlc.

I don't understand your problem. Do you have general problems with 10bits H264 and uncorrelated subtitles problems or just subtitles problems when playing 10bits H264 ? You'll have to be more specific about this part: "eat some letters of the phrases in the subtitles when the video leads" ...

What is the nature of the problem? The seek is (relatively) fast but you have macroblocks everywhere or the player just hangs for a long period before it starts a correct video? or both?

What do you mean by "smooth" you see macroblocks or it's slow? There are many reasons that could explain both.
Anyway the verbose logs (tools->messages set verbosity to 2 then start playback) could help us diagnose the problem.

Well you could try to enable GPU decoding (save and restart vlc). Unfortunately your logs don't tell much all my MKV work fine, if you had a problem with one file or one set of files I could ask the file to see what's the problem but if it's all your files, even the one that used to work, that are b...

Do you use GPU decoding and did you recently update your drivers? There are some problems with the latest catalyst

Could you paste the verbose logs tools->messages set verbosity to 2 and then start playback (from stop mode not pause).

Ok, I'll download the file and check that.

Try to disable GPU acceleration. I fear it's a driver issue.

And set verbosity to 2 before you start playback.

Is the audio codec dts?

Try tools->Customize Interface

I'll check that thanks for reporting.

You can look at the logs (with -vvv or tools->messages and set verbosity to 2) but I'd say that you most likely miss packetizer and/or are using codecs unsuitable to rtp/rtsp streaming.
