Why i get antialiased subs in MPC?

[3ngel]

Hi,
here's a strange thing. If i load directly a sub through the menu "Load Subtitle", the subtitle appear antialiased (almost blurry), but if i load the .avs (that uses the same subtitle library .dll) throug the MPC i get right not-antialiased subs.
I don't want MPC antialiases the subs. How can i resolve?
Thank you.

EDIT:
It's definetively a problem of internal MPC subtitle filter.
Using the Directshow Vobsub.dll all is fine. At this point there is a way to disable by default the MPC internal subtitle filter? I'm not able to find one.
Thanks

EDIT - EDIT
Ok i managed to disable the internal MPC filter.

You could try adding Media Player Classic to your 3D program settings and tell it not to AA
