Finally done with backing up all my DV tapes. They had been lying on my table for years. Other than laziness, it was because I do not have proper software tools to do that efficiently.
This time, I found Exsate and DvDate. Exsate captures video from camcorder into separate files split according to date codes / timestamps. This way I can browse through the different scenes easily. Before using Exsate, everyone of my DV video was captured as a single big file (>10 GB). It is a pain to browse and backup this file into DVD.
