I am preparing to make my first attempt ever to put video on blank DVD-R discs. The discs are Memorex 16X 4.7GB 120 minutes. However, I see nothing on the package that says the discs are formatted. When I put the DVD-R in the DVD-R/RW drive (D) on my computer nothing appears on the screen. However, the light on the DVD drive does flash a few times but that's it. When I go to My Computer and double-click on the DVD-R icon, the message "D:\ is not accessible. Incorrect function" pops up. That makes me think the disc has to be formatted. Presuming the discs have to be formatted, how is that done? I have searched for "formatting discs" but all of the hits that come up talk about things other than formatting. The computer I will be using is running Win XP Pro. Thanks in advance for your advice.
