Marvel's Mightiest Heroes DVD Release... Do anyone have a clue?

I'm kind of new at this blogging thing so hear it is - A couple of years back there was mention of a DVD set for the 1960's animated series called Marvel's Mightiest Heroes which back in a day ran Mon-Fri with Captain America, Iron Man, Hulk, Submariner, and Thor. The animated shows were done in 2-D but they remain to be a classic among Marvel fans of old school. My question is why is it taking Marvel so long to get this DVD set on store shelves!

you get a better dvd from Canada

Thanks MutenRoshi, I live very close to the border and I just might do that, is there a certain DVD vendor or media store I should look for?
