Is it the fixed cup that's stuck? What tool have you been using to try and remove it?
I couldn't shift mine with Sheldon's vice technique (I did chip my paintwork, though.) I'd recommend the Campag fixed cup tool and a second, sturdy pair of hands to hold the bike. Stuck parts always seem to surrender in the presence of two people. I think it's easier to commit to maximum effort when there no danger of the frame moving.
