new law a FECAL matter

Something about the DVD filtering measure Bush quietly signed today stinks. The Family Entertainment and Copyright Act creates an exemption in copyright law to protect one Utah company that sells a filter for DVDs, censoring their content at $5 per month. Now I am not going to come to the aid of Hollywood on their "understanding" of copyright, nor do they need any help. But apart from the two obvious problems with this new legislation - namely that it supports censorship, and that it aids only one company, Clearplay and cracks down on their competition - I wonder why this kind of law is even possible under the current interpretation of the US constitution... And Hollywood product without sex scenes, violence and foul language? What are clients of Clearplay going to watch?
