The main problem with manually editing movies myself is that I have to see the stuff I'm editing out in order to do it.
I don't let my kids watch movies - with Clearplay or not - unless I've already seen it, I'm watching it with them, or it's rated G. Sometimes I'll let them watch a PG movie that I haven't already seen after I've checked kidsinmind.com to see what's in it, but then I watch it with them so I can turn it off if I decide to.
Anyway... Thanks for the suggestions. I'll give them a try.
