Never, ever burn a CD/DVD

Never, ever burn a CD/DVD at the highest or lowest rate available. Pick a burn speed in the middle of the min-max. If you burn at the max rate, your “burn” may not produce enough contrast between the bits on the DVD-r. The same is true for burning too slowly, you may overburn the bits, again not leaving enough contrast for the reader to discriminate the data well.

Compatablilty: I enclose a card with all my DVD deliveries stating that “if your DVD player is more than three-years old, it may have difficulty playing recordable DVD discs”. Ironically, the cheaper, newer players generally play anything I put into them.
