Apparently your Plextor PX-W1210TS burner is supported by InCD.
Does Nero work correctly on your box? If it does, so should InCD.
You should uninstall both InCD and B's Clip (and other packet writing programs, if any) via Add or Remove Programs. Then download the latest InCD 3.52.40 from Ahead's site
www.ahead.de and install it.
Sometimes InCD doesn't install properly, in which case you may need to unpack the self-extracting executable file to an HDD directory and run the setup from this directory; see S7 in the InCD guide

You may have conflicts between InCD and drivers installed by other burning programs or plugins. It may take a while to detect and resolve such issues. Have a look at the InCD troubleshooting guide
