Your drive seems to be an OEM version of Samsung SH-S182M. That should do the bitsetting thing automagically. Have you already tried burning a DVD+R and checked the booktype with Nero CD/DVD Speed (use the Disc Info tab for haveing a look at)?
Also, ImgBurn and Nero support bitsetting with Samsung drives, but there might be some difference between OEM drives and retail versions. Make sure, you have a disc inserted before you try the bitsetting tools.
