Digital copies are codes that you add to your iTunes, VuDu, Flixster or Disney Movies Anywhere account to be watched via smartphone, tablet or computer. This auction is for the code that will add the movie to your digital library.
It's a one time use code. But if you have more than one device, it'll share. So like I'm logged into the app on my phone and ipad and it has my digital library on both.
Dmr code is not included. My parents actually gave me this code from their movie, I already have one. So I don't know if it is a sd or hd code. I'll try to find out for you though!
