I think some of you may have missed my point..I have bought cds that I don't like..but if they are simply a matter of taste then I agree, buyer beware, however, if they are simply sub-standard then I do believe that the artists must bear some responsibility. To use your exampleof a video..If I don't like it, that is one thing, if it is so badly produced as to be unwatchable...that is another.
By way of a PS..why do guests with whom you disagree get chided for being guests when "being a guest is not the issue?"
