start the program before you want to burn something onto DVD+R and choose DVD-Rom in the "Change Book Type to" box.
Then click on CHANGE. You get a new window. Click on OK. Leave the program running, and start your burning program, (IE Nero Recode) and burn the disk. Afterwards when you check the disk in a program like DVDinfoPro, it should say that the Booktype was changed to DVD-Rom.
With my Stand-alone Philips player, it didnt make any difference if i changed the Booktype or not. The DVD was readable, but it has issues when I tried to go back to the menu. DVD-R works fine. But this is only with my Standalone. Others have had better results. I have the Liteon 851 Burner also.
