According to Q-Suite the book type for my DW1640 is set at +R, +RW, +R DL. Should I change this to DVD-ROM since I only use -R media. Or would not matter. The DVDs are played in mostly newer player but they are also sometimes played in an older player. Any input would be appreciated. Thanks.
It would probably be wise to set it to DVD-ROM if you can, just in case you get some +R & forget about it.
