I noticed that there are settings for things like deinterlacing in the FFDShow Mpeg-4 codec settings.

There are also some settings for deinterlacing, scalling, ect, in the Media Player Classic "Options" section.

Does one superscede the other? Or does it try to scale/deinterlace it twice?

Thanks

it do it once!!
the codec do it and mediaplayer option are only interface to configure the codec!! if mpc is well done it should apply the modification(if you made it in mpc option) to ffdshow!!
