I'd guess that cost is also an issue. The Canadian market is a tenth the size of the US but is spread out across the entire continent. One of my startups ships kids books. We pay $8 to ship from Toronto to Vancouver using Canada Post and that's with a large volume discount, but if I want to ship to the US using USPS from our New York distribution center, I pay $2.30 to anywhere in the lower 48. Also, the US deliveries take no more than 3 days, while Canada Post takes up to 5 business days - and that's expedited. Having said all that, why bother setting up the logistics required to ship DVDs when you can just stream them to a population that is heavily wired and internet literate.
