In Tiger, you go to About this Mac/More Info/Hardware/Disc Burning and look for supported DVD write formats. I think you're looking for "+RW DL". I think. I'm pretty sure mine is capable of burning Double Layer DVDs, but mine only says "+R DL". (Since single layer disks are way less than half the price of double layer disks, I see no point. You can compress file sizes to fit a regular disk for most purposes. If it's so big the compression causes problems, I just use two disks.)
