How about the quality of around $12X USB capture cable? I also want to convert the DV tape to mp4 H.264 compress. For NTSC system DV cam recorded video there is no problem for me, you can also use win10 movie maker for simple conversion & editing. But I have some PAL version DV cam recorded video, the video was found abnormal when I use IEE1394 connected to the PC. How can I fix it?
