Philips DVD+R 1-4x spindle



Just bought one of them, 25pieces got home burn a dvd, get ready to burn a second so i notice in small letters the following:

Before using this disc in a 2.4x DVD+R data drive, you need to check how to get the required firmware upgrade. Full details can be found in enclosed booklet.

When i visit the site mentioned or the philips site (i got a philips burner DVD+RW416) i dont see any mention of a firmware upgrade or anything…
