I just recently purchased a ReplayTV 5040. I set up parental controls to filter V (violence) shows for my young kids. However, when this kicks in, there is very little time in which to type in the password. After that, the screen flashes crazily and I lose all control of the ReplayTV...can't change channels, select menus, anything. The only way to regain control is to turn the unit off (or unplug) for a good long time (5 mins). After that, sometimes it just comes right back on where it left off (flashing, locked out) and I have to do it again. This is really annoying. Everything else seems to work just fine. Anybody else have this problem?
