For DV playback, you want a broadcast monitor (or a TV if you can’t afford one). You go firewire out from the computer, then transcode it to composite or Y/C through a dedcated box or camcorder.
The two approaches that come to mind would be to render out the bits you want to compile or delete out the parts (Ctrl/A Delete) you DON’T want, then group the elements of the remaining segments.
