VLC uses internal codecs for MKV. If you are using W7 then you don't need any codecs for mp4 or mkv playback. You'll just need a splitter like Haali (This is the W7 version, both x32 and x64).
As mentioned uninstall everything (including BSPlayer as it downloads codecs in the background). Install a splitter for MediaShow players and then use the Preferred DirectShow Filters Tool for Windows 7 to reset what codec is used.
The problem is that when you install a codec pack you never really know what they are doing or changing. Ken is trying to get you "reset". If you uninstall everything including VLC and then reinstall v1 as he suggests and still have problems with VLC then the problem could very well be the file not the player.
o.k i am uninstalling everything... and will install only vlc...
with only vlc still some of the video files cannot played...
seems like there may be some remnants of files left after the removal of the variuos players and codecs. He can try removing everything again, then running a cleaner like CCleaner to make sure any orphaned files are removed. An option is to use a third party uninstaller like revo uninstaller (it is free), but it is a very robust application that makes sure to remove anything associated with an app when performing an uninstallation. You can get it from here http://files.getdropbox.com/u/976813/revosetup.exe
here is the official revo site: http://www.revouninstaller.com/
For ccleaner get it here
www.filehippo.com you will see it in the list. Once you have done all this, follow Mikinho's advice.
Recap:
Install Revo
Remove whatever you need to
Install and run CCleaner
follow Mikinho's advice
Just as a side note, MKV is a container, so VLC can natively open MKV's it doesn't necessarily mean it can decode the audio and video. Although VLC supports almost every Video and Audio format meaning it shouldn't be an issue. The fact that MKV is just a container is the reason it is such a bummer Microsoft didn't implement it into Windows 7 natively. Probably some copyright issue crap...
