I noticed the Tudors under the Tv entertainment section of the dvr and being a history fan decided to take a look. I have the NR/AO lock enabled in the ratings lock and guess what it played without any request for the pass code. If any of you have watched more than 10 mins of this well made drama will know it's not for a young audience. How do I lock this so my kids do not inadvertantly select one of these. I also noticed it can not be deleted so I can't do that. Supervision is the best remedy but we like to have a DVR by the fact we only record programs that are kid friendly. This is how it was when we had Tivo. Is there any way to lock the TV entertainment menu option.
