A little addition to DVD_ADDICT's post is that the automatic bitsetting applies to both DVD+R SL as well as DVD+R DL. So as long as you use +R media whether it be single or dual layer, you will get automatic bitsetting to DVD ROM for the disks that you burn.
Unlike say the BenQ 1640/1650, there are no user selectable options to manually set the bit to anything else other than DVD ROM using DVD+ media with this 111L firmware. There are some people who still confuse (not DVD_ADDICT though ) the standard 111D/111 firmware that still does automatic bitsetting of DVD+R DL with that of the bitsetting of also the single layer DVD+R that is available only with the 111L series of firmwares for this model.
So as far as bitsetting is concerned, you now have everything automatic with this 111L firmware, enjoy
