If your HDTV has a FireWire (1394) input, you may be able to use the FireWire connection on your camcorder (found on most miniDV camcorders) to connect digitally. If this works with your camcorder (and it doesn't always work), it produces the best-quality picture on your HDTV.
Even if both your HDTV and your camcorder have FireWire connections, you may not be able to use them to connect the two together. Check your camcorder's manual -- many times you can only use FireWire for connecting to a PC.
You can use the FireWire connection to send your video to your PC, edit it (using iMovie on a Mac, or Windows Movie Maker on Windows XP), and then burn your own DVD or copy to your D-VHS recorder. This gives you a very high-quality video source for HDTV based on your home movies.
