I just bought a Benq DW1640 due to its good rating. After i connected it and switch on the pc, it is auto install by winxp pro. However, it is auto install as a cdrom drive install of a dvdrw drive. Thus, i uninstall it and try to manually install but to no avail. I tired to look for the Benq DVDrw drivers but unsuccessful too. Pls advise. Thanks!
