Just out of curiosity- how do they record to DVD? Does it first get captured and then exported to DVD or is it on a direct to DVD recorder? I ask because a far simpler system would be to capture to DV or at least direct to hard drive. Then you’d have a much much cleaner, much much easier to re-edit system. It could even be setup to run completely automatically and organize itself by date and time. DVD archiving is just that- archiving. If you are wanting to go back and re-use material often, DVD is IMHO worse than VHS because it’s not what it’s designed to do.
