Roxio Titanium Toast 7, which I have, was no help for DVD DLs because it had no 2.4x speed to select. I simply suggest that one follow the recording speed printed on the disc itself or on its package. Macintosh help says that earlier SUPERdrives would record DVD-R but not DVD+R. Such an external drive could read CDs and DVDs, play Blu-Rays, and even burn discs if that’s what you want. Many regular DVDs say 16x speed on the top of their disc. How do I burn a CD on my Mac without a CD drive Option 1: Get an External Drive To do this, you’ll need to buy an external disc reader that plugs into your Mac via a USB cable. I use Disk Utility for DVDs and where the window asks for speed of recording, i.e., best and 2.4x and 4.0x, the DVD DL-regardless of brand-says 2.4x so that is the speed of recording that I select. I have read the replies elsewhere that tell to try a low speed, such as, 1x or 2x or 4x and so on. I have read the posts that recommend blowing compressed air into and over the CD/DVD laser lens in its compartment. May I suggest, in my humble experience, since I have read other replies elsewhere to questions similar to this, note the speed on the disc.
