Is it possible to turn a dvd+r into dvd-r using image burn?

How can I turn a dvd+r into a dvd-r 

[dbminter]

You can't.

Oh dam

[LIGHTNING UK!]

Assuming you're talking about the physical discs themselves.

It's like turning an apple into a banana.

If, however, you have something burnt to a DVD+R that you want to burn to a DVD-R, that's something totally different.

Oh, yeah, I didn't think of it in that way.  If you have a DVD+R and you want to "convert" it to DVD-R, you can't physically transmute the DVD+R to DVD-R, but you can copy the DVD+R's contents to a DVD-R.  Just insert the DVD+R into a drive, use ImgBurn's Read mode to read the DVD+R to an image file, and then use ImgBurn's Write mode to burn that image read in Read mode to a DVD-R.
