While I agree that using the DVD player as a babysitter is definitely a problem that could result, we also need to remember that there are people who would use such a device responsibly. The fact that such a device exists also indicates just how problematic the MPAA rating system is. The process is so politicised that the ratings become meaningless, besides the fact that a PG-13 is meaningless to begin with. "Parents Strongly Cautioned?" What the heck is that supposed to mean, anyway?
