This link was posted on a Me-TV board a little while ago; it's a blog post specifically about the DS rumors:

Wow, that was way back at the beginning of August. And not to put a damper on the possibility that MeTV might add DS, but the announcement that came out back in the summer after that post was made was that beginning on some date in September MeTV would be adding
Gilligan's Island and
F Troop, which are now a part of their line up, and maybe some other comedy. I forget exactly because when I saw the shows they weren't anything I was interested in adding to my already full TV viewing habits (not that I don't like shows like
Gilligan's Island and
F Troop - I just don't have time to fit them in). But if that was the announcement that the blog post refers to, there was no mention whatsoever of DS.
