Personally, I'm not sure if I'll do anything with the SE disks. I doubt I'd watch them but the idea of sending them anywhere is starting to lose it's luster. Maybe a petition is better than a mass sendback. Less effort on my part, just as good. A mass sendback would only work if enough of us do it and somehow the media gets wind of it. So, ultimately it sounds like a waste of time.
So mine will probably languish in the box just like many of the bonus discs for some of my other DVDs. Content I might watch once and then never again. In this case, just plain never.
