The title literally says "[Overwatch] Saving highlights in MP4 format fails, needs mfreadwrite.dll.MFCreateSinkWriterFromURL", so how i this different from this one?
Apparently the game changed, trying to save in MP4 doesn't just fail now, it crashes the game. A stub makes the crash go away and return to "previous" behaviour.
