Well most of it is painstaking work but I've just upgraded by Adobe Suite to CS 5.5 (yes fully registered)
so I now have the handy Rotobrush tool to work with you just paint the area you want to roto in green press alt and paint red in the areas you don't want luckily it's pretty good at edge detection and in the tools section you can add smooth, feature, choke and such to the matte to get a really nice roto. But previous works I have done is mainly just painstakingly adjusting anchor nodes to a roto mask.
