As Chris and I have stated before, the DVD business model no longer works. The higher the premium charged, the lower the number of takers.
As for using outside services, that's what we've always done. But these are designed for high volume fullfillment, and for small volume the costs skyrockets. The higher the price, the less takers. The less takers, the higher the price. Regretably it's a lose, lose situation.
We expect to be able to provide HD quality downloads within a year, so that need will be addressed.
