I just recently started printing DVD case covers for my DVDs and CDs.
Here are the links for the DVD templates.

I edit it in photoshop to a canvas size of 8×12 inches then have it printed by a local photo lab on 8×12 paper and just cut the excess with a scissor or paper cutter. (I find 8×10 is too small).
Here are some useful measurements for DVD and CD cases.
