I only glossed over the DRM-specific code, since I'm not familiar with it.  However, I do have one
general complaint.  Except for a line or two here and there, none of the code is documented.  I
would love to see some patches posted in the future that addressed this.

Patches 52 and 60 are missing from this posting.  I do have comments on patch 52, which will
hopefully show up soon.
