Do you mean like one of the sites that has the file on a server somewhere in Sweden and lets you watch in crappy quality in a flash player? Or do they mean Netflix or something. If the former, then this legislation might be effective to stop them. If the latter, then they have the economic means to pay for convenience, which is the whole point of SOPA: make piracy inconvenient.
No I mean watching it on Megavideo (where you have to reboot your router every x min, watch it in small crappy format). Somehow "google a torrent file, download that file if it has enough seeds, open it with the torrent client and when it's done it will be in this folder on your hard drive", is too complicated.
