Some MKV Files is Freeze once Per Boot

Codec , i already use k-Lite for many years, but first time i have this problem when i finish boot, i want play mkv files , suddenly freeze or Application Crash, the mpc is appear but the video not appear, when i move my mouse and left or right click , suddenly freeze if i always click click click , have a *beep* sound after waiting 5~10 Second freeze , but when play another or same mkv after freeze is smooth , is annoying like this when after boot, i already try change RAM , still no use ... but when i try using CCCP installs it's own version of MPC ... all smooth , not having an freeze problem , i already try update my K-Lite too and reinstall, and try reinstall VGA... but still no use , not worked at all

Need Help, Thanks...

Something is slowing down harddrive performance during that first play. It could be your virus scanner. Which one are you using? I can recommend Microsoft Security Essentials.

Disabling DXVA might help as well.

Changing the video renderer may also help.
MPC options -> Playback -> output

yeah when i use EVR Custom Pres only happens freeze , but why CCCP MPC can use EVR Custom Pres without problem , i using Kaspersky Internet Security 2012, when i close the av and try to play video , still have the problem ...

why if virus scanner but other extension can start without problem ?

Do I understand correctly that the freeze does not happen when you use a different video renderer? If so, did you try disabing DXVA?
options -> internal filters -> uncheck "H.264 (DXVA)"

DXVA is disabled by default in CCCP. Actually in K-Lite as well, but there is an option in the installer to enable it, which you might have used.

MKV files usually contain H.264 video, for which you can optionally use an DXVA hardware accelerated decoder. Other formats like AVI usually contain MPEG-4 video. That is the main difference.

but when i install k-lite i didn't checkbox that H.264 (DXVA)

I don't know what you did and didn't do. I leave all possibilities open.

I see that you are now having the same problem with CCCP as well.

You should try completely removing Kaspersky to see if that helps. Scanners usually only scan files once, which could explain why only the first run is slow.

yeah , i try CCCP too , but now freeze too , then i afraid if something with my Notebook Hardware problem , now i try VLC Player , so far not happend anything , i really like using MPC than VLC , but it's annoying too if freeze every open video after boot, this problem only happend at mkv files, but some mkv files not freeze too, what should i do ?

of course i already try uninstall Kaspersky , reinstall VGA ...
but not work at all ...

if you search google, you can fine other users have this problem too ... it's annoying --"

Bumpty Dumpty

You could try using LAV Splitter for MKV instead of Haali.

Does your notebook have a tool to configure power savings mode? If so, try putting it in hight performance mode before starting playback.
