It's hard to keep track of all the videos, best way is to put a big huge watermark on the video, possibly right in the center (but drop the opacity), doesn't mean people won't rip them, just that they can't crop it off. Reporting to YouTube is tedious as heck, that's no help either. The form to fill up can't be auto-completed most of the details are all the same, just video being reported and original video URL are different, yes you can report a few videos (up to 4 I think) per report but sometimes the amount is just too much. There must be a simpler way, YouTube has the complainer's (it must be the original content owner) ID so what's the purpose of all that verification stuff, if a fraudulent complaint is made the complainer gets penalized instead, people won't simply make false reports.
