check the related email michael it means they disabled the video from monetization and decided that they are somehow not worthy of such a thing lol.
You can try but write a message in wordpad with all relevant links
eg: software you used .. yeah stupid.. but
the videos are from people of different channels just a guess but they might think because they dont listen and watch really that you took them without asking so.. for each video get written permission from the person and send them that .. *gasps for air and wheezes ..*
any sound like say you know someone dropped their cat and it howled you need to proove that is allowed ..
or when the bus goes by..
sorry being silly but basically take the videos apart piece by piece give them info if you can manage to do so without loosing your mind and then wait for oh 4 weeks where they answer you vaguely and then ask them to stop cutting and pasting responses and help out for "reals"
and well try to pull out of them exactly what the reason is.. sometimes you get a human being and they will tell you but its a lot of work to get that far..
good luck. I know I simply can't be bothered to fight with them over this crap. At the end of the day the potential gain is simply not worth the time effort and exasperation to deal with it
