The first feature I do not like is when a recorded show/movie is over you are prompted with a pop up. You can either delete, go to my media or click live TV. The delete button should not be listed here. This is why, I do not know if it is a bug or setup this way, but my tv1 will protect everything I ask it to. The tv 2 will not. My tv2 is in the kids room. They will watch a show and delete it not knowing any better. If the system worked the would not be able to without the password I designated. The second is how you setup a protected show/movie. The 722 is much better in this regard. I could just choose a show click on it and have the option on the right to protect. With the 922 you have to edit all, click on the show, edit action, choose protect, then remember to close edit. If you do not do this then it doesn't work. It Seems to be a rather round about way.
