Thanks for the info,
If I understand this correctly, there is an internal ffdshow in MC16 in addition to the external one installed on my computer? This will explain that even when the external ffdshow was uninstalled, MC listed ffdshow as the video decoder (auto configured, and in grey) when playing mkv files. It does not explain, however, why making the external ffdshow unavailable to MC, also turns off the internal one. There must be some kind of interaction between the two.
I have no problem allowing ffdshow to be active for MC16, as long as its settings are your "internal settings" and not my "external settings" made to upscale Lo.Def video.
What started this in the first place was, for the first time using MC on this computer, that I experienced quite extensive stuttering when playing 720p mkv files.
So my question now is; what causes this stuttering that I thought was an overload of my processor?
