Problems with .wmv files.

Hello,
Recently I have encountered a problem with playing .wmv video files with K-lite codec pack. Problem was, when I had 9.75 version installed, that files were stuttering (if they were 720p or above if I am not mistaken) or that they would just give me an error and MPC-HC would turn off if I was trying to use seek bar.
I tried to reinstall codec pack, downloaded the newest version (mega codec pack one) and now .wmv files wont even start. Tried to change codec from ffdshow to LAV for wmv3 (windows media video 9) but it doesn't help at all.
Of course, other players are starting them just fine, but I don't want to use different players just for that one file type.

Can someone tell me what do I have to do to fix this problem?
OS I'm using is Windows XP SP3 and I have Windows player updated if that's of any help.

Thanks in advance.

WMV files are played using codecs from Windows by default. The pack does not use ffdshow or LAV for them unless you change the settings. So please test with installing the pack with default settings.

Yes, with default settings they start normally. But then there is another problem, videos are unwatchable, picture is green/purple/filled with squares. Of course, when I activate wmv3/9 codec for those videos, picture is clear, but the original problem appears again.

I don't see anything in the list that should be a problem for WMV playback.

The weird colors problem with the Microsoft codec might be related to hardware acceleration.
Get the WMV9 PowerToy tool from here:
http://alexzambelli.com/WMV/
It has an option to disable hardware acceleration for the Microsoft WMV decoder.

An alternative solution would be to use LAV for both decoding and splitting. You can set LAV as preferred splitter for WMV with the Codec Tweak Tool.

Thanks for mentioning hardware acceleration
PowerToy didn't help much regarding that, but I found that it was being enabled in Tweak Tool under "Various Tweaks".

Everything works fine, tho still, seeking is slowish but its better that then strange colors or stuttering...

Thanks again.

Slow seeking is kind of normal for the WMV format. It is related to how that container format was designed. It is especially noticeable on slow computers.

Seeking might be a little bit faster with LAV Splitter.
