Basically Red isn't good for screening (in my opinion). Human skin contains a red pigment which is extracted by the software. I use a greenscreen - personally i'd say thats the way to go but some people say blue.

Hope I helped!

I just remembered - you could use a garbage matte to take away the red screen. But that would leave you masking the character frame by frame (This will work well on Clab - if you have the time!)

As you have discovered, Red is a color which is nearly impossible to key when the foreground subject contains people. Elliptical Productions has basically explained why this is. Red is one of the primary component colors of skin tones; this is why traditionally compositing has been done using blue or green screens. Typically green is the best option for DV footage, as the green channel records more color data that the other two, meaning you can get a cleaner key.
