1. BluRay support is not native to 7 so you'll have to add that with software titles. This software rarely comes with the bare drive.
2. Closing a session is not the responsibility of the drive. It's done by the recording app.
need help my LG CT21N supposed super burner does not recognize blu-ray disks writes on standard dvds but does not close them out
Error message for blu-ray disks "insert a writable disk"
