My 1st question is regarding the types of DVD-/+R. Is there a difference in suggested uses for the DVD-R verses the DVD+R. I have been told the -R is for data and the +R is for video. Others have told me it makes no difference if my DVD drive can handle both. My 2nd question is regarding DVD's too. Can DVD's be written on and/or labeled without fear of loosing data, again I have heard that markers and labels can penetrate the dye layers and destroy data, Is this true?
The difference is not really that big of a deal when using DVD drives that support both. You'll only have to watch out when making DVDs intended to be used in a DVD player. Which type, -R or +R, is more compatible varies between individual units (and generally they're older units). You'll have to experiment and research the target DVD player to know what works best. With really old DVD players, you may find that neither works. In that case, you may have to buy a newer player. A good site for information on this is VideoHelp.com. Just be careful of copyright issues when following some of their guides.
I've heard the same claim, in regards to markers penetrating the plastic of a DVD. However, I've never seen it actually happen first hand, and I write on all my CDs with a Sharpie. I wouldn't worry about labels. They come from some manufacturers with printed stick on labels. I'd assume they'd consider this, since they produce many more discs then an individual ever would, and I'm guessing that kind of volume would be more prone to seeing the issue.
