I've been using CyberLink Power Director on my Win 7 x64 PC and like it a lot. Imports most formats directly including mpeg VOB files, supports up to 16 tracks, provides a very nice selection of output options including Blu-Ray, very intuitive editing controls, fast rendering, high quality output, very rarely crashes. I've used Premiere Elements and Corel VideoStudio Pro X2 and I like it much better than either of them. No experience with Vegas or Pinnacle, however.
