I need help with my VLC player

Convert MKV to Better Compatible MP4, AVI, MOV Video Formats

Compared with MKV, the videos formats AVI, MOV, MP4 are more compatible with PC, MAC and portable devices and can be played by VLC more simply. Therefore, it's better to convert MKV to those more common video formats to play MKV with VLC while avoiding sound and subtitle problems.

I don't think converting is the solution of this problem. I mean these days so many video files comes in MKV format. So converting all of them to any other format is not an easy task. Plus converting big media files is very time consuming process. So it can take lots of your time. 

For me I never face any kind of problem in playing MKV format videos in my laptop and desktop computer. They are working quite smoothly. So I guess instead of converting better to try another way for playing those files directly.

If your .mkv video won't still play in VLC player. There is something wrong with the application. You better update it or uninstall it and then reinstall it. Probably there are bugs in your present VLC player.

I think ultimately, reinstalling VLC player to the latest version would be the best option. Do you know any reliable website from where I can download it safely?

I again switched to a new player. Even after installing the proper codecs some mkv videos were not properly rendering in my VLC player. The issue is, for a small duration ( normally 5 seconds), the video becomes pixelated. Initially, I thought it was the issue with the video, but when I played those videos using a different player (the one that comes default with k-lite codec pack), the video played perfectly. So I switched to this new player- Media player classic( default k-lite codec pack player)

I had similar problems with VLC and I was not sure what the problem was so I just downloaded a new, updated version altogether and now it plays mkv files with no problem. Maybe the older versions don't have the ability to play such files. You can also consider using other video players which support mkv files.

Try to update first the player, maybe some features aren't available in your version. But if it doesn't work, try to troubleshoot it, preferably online. You can also download other video players which can support mkv files.

If you VLC player doesn't work, better uninstall it and install a new one. It is probably not updated. You know video player of any platform should also be upgraded and it could be availed its update from the web. Check always an upgrade of your VLC.
