The story behind that, as far as I can tell, is that they did all of the PPV editing for their on demand channel (which is why it was all set to go for the network launch) and when they did the editing for that they didn't have a working relationship with Jimmy Hart who had some say in the matter and they didn't want to pay him because he was in/working with TNA.
ECW is a lost cause. That shit was straight up theft and the rights to all that music is literally worth more than the ECW back catalog.
