I am a heavy user of parental control as I have two teenagers in the house. There are a few things I wish D* would do different with parental control on the HR-21. First of all I wish I had an option not to block titles. It is annoying going through my DVR list and having to unlock the system because a title is above the parental rating limit. Also I wish there was a way to access the "unlock all, unlock 4 hours sub setting without going through the menu. It would be great if they were listed on a sub menu available on the "this program is locked message". Hope this make sense. Does D* have a way to submit suggestions? This sounds like something that could be changed with a software update.
