I just installed my new LG GSA-4081B http://www.lg.ca/computer/prodSpecification.asp?p=3336 and have successfully burned 3 Memorex 4x DVD+RW discs. However, using Roxio, and selecting 4x burn speed, it will only burn at 1x speed. Since LG recommends Fuji or TDK DVD+RW blanks, I tried a Fuji 4x DVD+RW and used Decrypter to burn. I managed to get 1.3x speed, but that's it. The main reason I bought the LG is for the 4x burn speed with DVD+RW. I've checked LG's website, and there don't appear to be any firmware upgrades -- the drive was built in Feb/04. Can anyone offer any advice on how to speed this baby up?
