By now, even the shittiest movie produced in the 90s has had so many tv runs, so many VHS and DVD units sold, that all production losses and fixed fees have been recouped.
I'm not so sure about that. The movie business is notoriously crappy - most movies never recoup their costs. It's the few wild successes that keep the studios afloat.
On the other it is true that the marginal cost of selling digital downloads of back catalogue movies is close to zero.
