I just baught a lg gsa-4163b. I so far love it. Just a few questions. I put the lg burner in my usb2 external enclosure, burned a dvd with it and seems fine. I later relized I had 102 firmware, and decided to update to 105 firmware. Is it ok, that I update the firmware while in the usb2 enclosure. Should I be concirned about using the usb2 enclosure. Everything seems to work well so far. Also is there any way to test the dvd for quality after burned, or this lg cant scan.
