Printable DVD-R. Dangerous To Drives?

I've been doing a lot of research on the subject and so far, I've got mixed results from people.

I currently use the Verbatim Printable Inject DVD-R media. However, I've got concerned recently of how this may be effecting my drive.

From what I hear some drives can become so hot that they can cause the ink to run, even on discs that have been dried for months and months. With the spinning of the disc this can throw ink on the lenses and ruin the player (or the XBox in my case which would be a real shame).

Then again, I've heard others who say there's no cause for concern after the disc has dried.

What's the real verdict. Am I putting my equipment at risk. Should I just switch to lightscribe and be done with it?
