ffmpeg (the application) reads and writes multimedia files
why should ffmpeg suddenly stop working well with monochrome ?
(and require the user to per file convert to monochrome when the input
 already is monochrome)

Also we talk about the raw video decoder here, i suspect this is used
for more cases than just avi

either way, as said iam happy to switch to using pal8 for monochrome
avis if people want.
I just dont know if people want that

Breaking DRM is a little like attempting to break through a door even
though the window is wide open and the only thing in the house is a bunch
of things you dont want and which you would get tomorrow for free anyway
