Category protected, however, individuals posts are not & buddypress pages too

Heya fab people,

Have a few questions I'd like to ask regarding the membership plugin.
I've been working with it and notice that even though category is protected (for stranger)
For instance, check http://resscity.com/category/video

The individuals posts related to the category is not:
http://resscity.com/category/video/you-cant-make-someone-change

Been trying to find a work around for this by playing with permalink settings, without any success though.
So I thought I post it up here to get any insights.

Also, one thing I notice is even though I restrict access to the buddpress pages, they are all still accessible to strangers.

I'm using Wordpress 3.0.4 multi site enabled and buddypress 1.2.7.

Thanks for the help!
