Currently I can use parental controls by program rating. I would like to be able to set start and end times for television viewing via the set top boxes, as well as by program rating. I would like the box to black out the screen at 9:00 PM (for example) on school nights and it can only be overridden by a parent with the password. Likewise, I want the ability to only allow TV viewing from 5 PM to 9 PM except on Fridays, where it can be 4 PM to 11 PM.....I think you get the idea. Thanks.
