There is no DRM on our downloads. One is free to burn them to DVD.
As for playing them on a TV vs a computer or iPod, this is going to be come increasingly possible as devices like Apple TV become widely in use.
We have to look to the future, not the past. DVD video distribution, with all the hassles of bulk disk replication, wharehousing, packaging, fullfillment, shipping, postage, returns, lost disk, mail delays, customs (half of our business is international).... all of this simply tells us that download is the way to go.
Just as five years ago we turned away from VHS videotape to a new technology called DVD, we now have to look to downloads as the future of non-broadcast video. No DRM, instant availability, much lower cost to the customer, ability to be played on a multitude of devices, from iPods to computer screens to TVs.
No, I'm afraid there's no turning back. We've been researching and planning this for almost 6 months, and the move is necessary. We will likely continue to publish at least another couple of DVDs, but the content will appear online weeks beforehand (maybe even longer).
We know we will lose some customers by dropping DVD distribution, and this is unfortunate. But the reality is we are now selling vastly more downloads a day that we used to sell DVDs in a week, so the writing is on the wall.
