How do I update the firmware for the DVD burner?
I'm having lots of problems with burning DVDs recently; I'm getting the message: This disc can’t be verified and might be unreliable. Try again using a new blank disc (error code 0x80020063).' I'm using Verbatim DVD-R disks - as was recommended on this forum - so I wrote to Verbatim to ask why around a quarter to half the disks on a spindle were being rejected with this message. They asked if the burner firmware is up to date. How do I check this, & how do I update it? I have the Apple update installer, so I would expect to get a message if something needs updating.
Thanks
