Last night I successfully burned 2 DL DVD's of data files from Windows XP (and 2 more tonight) when I was booted into OS X - but when I reboot into Windows XP > put disc into E drive, it reads it as a blank disc (I even gave it time to mount itself in the drive - no go). So tonight I installed that Roxio 8 DVD burner software that I have laying around in my office into Windows XP, and tried using it (I used the Drag to Disc) to burn a folder containing these data files onto another blank DL DVD - The burn failed; it said something like "copy was canceled or there was not enough space to copy the files" - I wasted a total of 5 brand new DL DVD's that I brought Friday so far! Pack of 15 DL DVD's.
And a couple of weeks ago I was successfully burning DL DVD's in my mac on my Windows side using burning software that someone on MacForums had found for me - it's Ashampoo Burning Studio 6 Free. All DL DVD burns using it on windows were successful until I d/l and used that Nero Drive Speed, take mac to Genius Bar, they said it was a software problem which they corrected/tested it (on the OS X side), told me to reinstall OS X - archive & install and Windows XP (which I did before doing these burns)
And I'm starting to wonder if the burn in Ashampoo failed b/c Ashampoo has a sieral number that I had to activate it? Only my Windows XP in my mac only has 29 days left to activate and I cannot connect (don't know how to set up my internet connection in windows xp) to the internet from windows to activate - but even if this was accomplished, I'd just waste more DL DVD's trying to burn from Windows XP. This is CraaaaaazzzzY!!!
Please get back to me ASAP - I'm very upset and frustrated
P.S. I don't want to have to have to take my mac back to the Genius Bar as it's in quite a distence from our house, I can't drive, too hard to take a bus/I'm hard of hearing/my mom (she took me with the MBP to the Apple Store at South Hills Village Mall) and she doesn't want to have to keep running back and forth there.
Here's a link to a thread about SuperDrives refusing to burn media on DL DVD's - one person said it did for a short time then conked out on her/him: Apple - Support - Discussions - Superdrive refuses to write Dual Layer ...
My MBP was ordered online from www.apple.com's online store July 8, 2009.
