If I were to purchase these two packages – Microsoft Viewer 2.0 and Toolbook, it is my impression that I would be able to put together MM "solutions" at least at some basic level for customers. This assumes that I just want to take text, video clips, and audio clips that have been created elsewhere and make them available in some method. Let us suppose that I want to be able to edit video and audio — not so much to modify but to combine/recombine clips. For example, take two sources of video which are of five minutes length each and combine them into a single three minute clip that takes pieces of each — but I don't need to change coloring or composition. Same for the audio. Can I do this with the above packages or do I need a third (or fourth package). If a third (or fourth) is the answer, which would you recommend? – Dan
