If I understand correctly, you are content distributors and video encoders.

So you sell copies for money and a promise to delete the copy after
it's use. That's like selling a book, printing "Burn after reading"
on it and calling yourself a library. Also the book shall not be used
for "unauthorized uses", e.g. put under a table foot, lent to a friend
or read repeatedly. The latter two cases may be solved by going to the
"library" and buying another copy, other can't.
Many people see DRM as an hybrid between a lock and a automagical fire
lighter.

This seems like a saner alternative.

Once a user has bought a copy, the copy has been bought and how
(often) he uses said copy isn't your probem. You've successfully
distributed and charged for the content. Job's done. A technical user
will probably be able to copy the video to permanent storage whatever
you do. Multi-pricing can also be achieved by other means, such as by
resolution crippling. Watermarking to aid with tracking down grand scale
pirates seems to be an OK thing to do.

Server load can also be reduced by e.g. P2P, though users may want the
price to drop in proportion to their uploads.
