Yep, found it.
I was assigning Full Control to D:, but that still wasn't working. So I checked D:\NPVR, which indeed was locked down to everyone but my personal user account. (I expected the top-level rights to act recursively.) Gave Full Control to that folder, and now recording AND LiveTV works a treat when the directories are set inside of that folder structure. So I'm fixed, yay!
