I'm not sure if the Weezer special is being included (though it sounds like it is), but if so, it's weird that that and the valentine special are being included. I thought that the reason why the first set didn't have both pilots was because of disc space, and both the valentines pilot and the weezer special are a half-hour long (none of the other season one features besides Sex and Violence lasted a half hour). If there ends up not being room for both, then the valentine special better be what's left in.
I wasn't even aware that Disney owns the Weezer music video. I thought that was owned by whoever Weezer is under contract to. Unless, of course, Disney owns Weezer's contract. If so, then I guess that it is good that Disney is willing to negotiate distribution rights for it's Muppet DVD releases, and I hope that Disney can someday get the rights to release some Muppet content that Disney doesn't actually own (like The Great Santa Claus Switch).
