I just saw a report of a firmware bug in Pioneer DVD recorders and DVD-R drives which can cause damage to both the disc and the drive/recorder if you try to burn using one of the new 4x discs which will be hitting the market soon. Pioneer has firmware updates available for download. You can learn more about it at http://www.pioneerelectronics.com/hs/ But these days I'm wary of downloading updates. If you install Windows XP Service Pack 1 then you agree to give Microsoft a back door to your computer to make any further updates they see fit. So I'm wondering if Pioneer has anything up their sleeves with this urgent update.
