Question about videos on Facebook.

This has only happened a couple times in the last year or so, but the more I think about it the more it worries me. Well I add tons of videos to my Facebook fan pages daily. And like I said, it's only been a couple times, but I have been "blocked" from posting for 24hrs for uploading a vid that was "copyrighted". Now what I am asking is, is there a way around this? A way to either check the videos first or a way to add/remove something to the videos to prevent this? Thanks!

its tricky.. to be sure get a bunch of fake accounts.. and upload it to one of the fake profiles.. if it stays then you know its good.. but you ant get around posting copyrighted stuff.. even if you were to slow the audio or whatever.. why would you? if your page is big enough it will get flagged..

Add intro, change the tempo etc.

@osmokes - The fake accounts, that's exactly what I do. The thing is, when it happens, it's normally on videos I uploaded MONTHS ago that some douchebag little "viral video licensing" company I guess bought and runs around the internet throwing a fit about it.
@Rotem - What software do you recommend for doing something like that?

What blows my mind is seeing pages with MILLIONS of fans that upload videos daily, and they don't seem to have any issues...

Thanks guys for the feedback!
