Redbox is not selling digital content they are selling a piece of paper that they legally purchased. This is not at all inconsistent or really comparable to not being able to resell a song that was purchased on iTunes. It's maybe similar to being able to resell an iTunes gift card that came along with the purchase of another item, which would pretty clearly be acceptable. DRM really isn't involved in any way here - the existence (or lack) of DRM would not change this situation in any way at all.
