Actually, it'll be broadcast at 4:30 PM. Prime-time in the US is 8 PM to 11 PM.
I think there area couple interesting things here.
One, if paintball is going to be on TV, part of that is only the television production company gets to film. That's just the way it is.
But, it does not look like that's the case here. Here, it looks like NPPL is doing the same thing that's been done before: Paying Fox to air their program. When you pay to air your program, there usually isn't a requirement that what you produce be exclusive (beyond not putting it on another network). And, NPPL is broadcasting the center court field live on the internet, so there obviously can't be an exclusive filming/broadcast deal in place. If there was, NPPL wouldn't be broadcasting live on the internet either.
But, if the film companies were offered reimbursements, I really don't see what there is to complain about here. Too many people in paintball think they are 'entitled' to be in business. You're not. If the leagues don't want you to film there events, then you either need to find a way to make them believe it is in their best interest to let you film, or you need to accept that you just can't be in the business that you want to be in.
It's also a dangerous precedent when one company starts taking actions because their friends in another company are upset about something.
