Won't work for FLOSS/CC licensed material, or public domain works. The distributor is not an agent for the copyright holder; she either has a license which allows redistribution, or does not need one to legally redistribute. So, your disclaimer is reduced to "I am legally allowed to redistribute this media". Which is pointless. It's inherently implied by the fact that you are redistributing the work. Unless you are breaking the law - in which case, why would lying about it bother you? Oh, yes, I am totally authorised to redistribute this media. And these genuine Rolex watches I am selling for $20 fell off the back of a truck. They are definitely not fakes infringing on trademarks, nor are they actual genuine articles which are stolen and being fenced, no siree!
