Does your company have a budget? If they can stretch to about £70 then you can purchase Adobe Premiere Elements 4 or whatever the latest version is and it will do all you want. It will capture your video, allow you to edit it and then give you the option of either making dvd's, putting it on the web or just making files to playback on computer. Before you purchase anything you should download a few 30 day trials of some of the software used on this forum and see which one you like the best, most are fully working and you may even get your documentary done in that time.
