To answer your question, MainConcept is actually the name of a company that specializes in developing video/audio codecs and also applications and plug-ins related to video/audio encoding. They're a subsidiary of DivX. Obviously, the House of Mouse episodes that had that watermarker were encoded with a MainConcept product.
