Is it under warranty or Apple Care?
After burning about 20 DVD's of an iMovie project, the drive will only burn one or two and then say it can't burn. I thought it might be a SW issue, but then I tried to do a backup using the .mac backup SW. The file was 10.4GB so it spanned 3 disks, but as soon as it got ready to copy it said it couldn't burn.
I'd bought a new pack of Maxell 8X DVD-R, could the new package of DVD's be the problem? Some of them work. Should I get some other brand and try them, I've always used the Maxell.
Also, I was wondering if there was a DVD cleaning kit they sold, maybe the laser is getting defocused due to dust or something.
