Change is never easy. The only way to attempt to change the delays in payment is by having everybody reading from the same playbook. In my opinion, it starts with videography students. Do all the schools and universities teach basic, sound business practices to future shooters?
Do shooters discuss payment arrangements when accepting assignments? What do you need to do in order to get paid? What steps do you take? Who gets the invoice? Do you need to send a W-9?
If a company tell you that they pay in 90 days when offering the job, you can decide to accept their terms or counter offer with your terms. Negotiation is part of the process. I think many of us see job offers as take it or leave it, sometimes it is take or leave it, but you have to attempt to state the way you do business.
I bet when we get a phone call offering work, the person offering the freelance job doesn't mention what steps you need to take in order to get paid. It's happened to me. All we want to know is how much.
You mention that networks have corporate policies that determine when they pay vendors. I'm sure if they want your footage there might be some flexibility in rules that seem set in stone.
I'll post links to a few articles from PDN. I hope it's not against the rules. Here's one.

My clients were not paying me on time.â€
Another strategy is to get clients to pay your expenses up front. Harrington does that. So does Jack Reznicki, a commercial photographer in New York. “I’m not a bank; money costs money,†he says. “I’m more than willing to wait on my fees, but the stylists are not waiting on my fees.â€

Negotiating Tips for a Tough Economy
January 02, 2009 Negotiating is the fine art of getting the best deal you can for an assignment, whether it's to cover a local event or shoot an international ad campaign. [...] photographers often leave money on the table or agree to bad terms because they lack negotiating skills. "In a down market economy, people say 'Yes' too quickly, and they undersell themselves," says rep Gregg Lhotsky of Bernstein & Andriulli in New York.
Even though the articles are photo based, it's the exact same principal.
