[BUG] x264 colormatrix option changes when "Overwrite input type scan" is enabled

[The_Tinkerer]

DVD often has special rules that differ from normal MPEG containers, which is why repacking into mpeg often isn't the brightest idea.

I guess, if I don't import directly from the DVD (using AnyDVD or a mounted ISO made from AnyDVD), I should be muxing into a single VOB file, rather than a single MPG file...
