According to this review

Screenblast Movie Studio 3 should work fine with Micro-MV. The article says : '"For Sony Camcorder owners whose format is the proprietary MicroMV format, Movie Studio fully supports this format. In the arena of lower priced video editing software, it is important to locate this feature. It is not a format commonly supported by many applications."

Hope this helps
