I'd assume they use some form of encryption through the chain - along
the lines of HDCP. Slightly easier to manage since the the target
market is smaller. Of course, these days a whole film could fit on a
portable hard disk and potentially each copy could have it's own
watermark to trace any piracy.

But once you factor in that many modern films are actually made in
the digital domain then the whole "cost of digitising" argument goes
out the window. In fact, I suspect very few films are made with
analogue techniques now - you know, like making masks, multiple
exposures, etc to make composites where you can see a faint image of
one thing through another because the mask wasn't 100% opaque.

I'd be surprised if there is cost parity - the resolution required
for a cinema sized screen is waay bigger than anything else around,
and then there's the amount of light required. The mind boggles at
what's in them - some mind numbingly expensive digital shutter panels
I expect. But of course, even if a digital projector is the same
price as a good film projector, it's not either/or - the cinema will
still need the film projector so any digital equipment is an extra
cost, not an alternative cost.
But this is getting waay off topic. At least over here we have a
culture where we expect to get multiple channels in the clear (eg
Freeview and Freesat), and subscribing to closed boxes (eg Sky and
Virgin Media) is optional. OK, there's some decent stuff only on
subscription, but there's enough to watch without.
