[gnomebard] ” I have used Sony DVCam tapes”
DVCam tapes will not work in a HDV camera
One of the most important thing about choosing a type of tape, is picking a bran d and sticking to it. Different brands of tape use different lubricants. Some are oil based, some are dry based. Mixing then can cause the tape heads in your camera to gum up, thus causing bigger problems. Even mixing different oil based tapes or different dry based tapes can potentially cause problems.
So pick a tape and stick to it.
