Bug with Restrictions iPhone

I attempted to enable restrictions for explicit music on my phone, but when i enable restrictions, it enables restrictions for everything like safari, youtube etc although i have disabled the restrictions for these applications. Think this is a bug and was wondering if anyone knew if a fix would be out for this soon or am i missing something here. Does anyone else have this issue?

explicit Video Ipod Restriction iPhone 3G

OK so I have some pretty explicit movies on my iphone ( which I put on myself, not bought through itunes ).My younger brother uses my iphone a lot and I dont want him watching these shows. So I wanted to know how I can tag these videos as explicit so that when I turn on the ipod explicit restriction these videos will not be displayed.Any help is much appreciated. PS im in Win xp if that helps.
