Fox released the first season as a simultaneous full season set and in two split-season volumes last June with much anger.  They replaced music and even went as far as to blur and edit a crucial scene in a bar fight which involved Colt Seavers.  (They poorly tried to mask the band playing on stage).  And nothing was stated on the back to reflect this either.  Even worse, there's been no announcement or even a sign that the studio has any indication that there are continuing this series.  I don't know how well this sold for them.  This is a childhood favorite that I would love to see continue and done right.  It has a good size cult following which would fit in well with your company.  If Fox has no intention of releasing the remaining four seasons and completely unedited, I hope this something that you can license from them.
