Here's a quote from the ESRB concerning the latest drama surrounding Manhunt 2:

"Parents need to be vigilant about monitoring what their children are downloading on the Internet and ensure that they are not making unauthorized and oftentimes illegal modifications to software and hardware that remove the controls the industry has so diligently put in place for their own protection."

Uhm, if your kids are savvy enough to modify their video-game hardware, be it through hardware or software means, I seriously doubt you stand even the remotest of chances of monitoring their media intake. Then again, I'm not at all convinced that monitoring media intake past a certain age is practical, possible, or even particularly fruitful. I had no problem watching movies and listening to music and playing games that my parents would not have approved of, and that was before the damn Internet.
