The other problem too is, you are asking a LOT of ECW fans to pay for a ticket to come to a one hour show of ECW, considering there are commercial breaks, that isn't giving an ECW fan very much for their money, cause I can guarntee ECW fans can give a crap about Smackdown.
At least with TNA they do 2-3 weeks worth of tapings in one night, so the crowd gets their money's worth.
instead of being obsessed with having a live show, Vince should just give ECW it's own night of taping and have them air the matches. They really should try to make the weekly show as authentic as possible.
