What's te best template to use when I want to publish the content (Scorm) in Moodle (not in a new window)?

Well, it's not so easy to choose the best template for Moodle. The tastes differ. Personally, I prefer simple templates such as "Minimal". But you can also modify any built-in template according to your needs and save it to My templates for future use (menu Tools - Add module to templates).
