DVD-RAM are more helpful, however, since it allows you to remove and retype on a specific sections of the DVD, this is not applied with DVD-RW. But they are compatible only with devices that produced by the manufacturers that provide the DVD-RAM format.

If the drive type is DVD-RW, you're going to use DVD-R and DVD-RW format discs. You cannot use "plus" formats, since those won't be suitable for your drive. Check your drive name to decide which format you are going to use. Use the System Profiler application on Mac to get information about your drive. Select application then "utility" then "ATA".
