I've been backing up with CDs, but my iPhoto Library has grown to where it's time to start to use DVDs. I'm totally in the dark as to which type of DVD to use. The System profiler tells me this about my burner:


MATSHITA DVD-R UJ-846:

Firmware Revision: FA0G
Interconnect: ATAPI
Burn Support: Yes (Apple Shipped/Supported)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW, +R, +RW, +R DL
Burn Underrun Protection CD: Yes
Burn Underrun Protection DVD: Yes
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
Media: No


So I believe that the burner can use -R, -RW, +R, +RW or +R DL

iPhoto Help talks about using -R. I also read in the Pogue book that I should be sure to use ther correct blank for the speed of the burner. I haven't been able to find the speed of the burner. Where do I look for that info?

Is this simpler than I'm making it? I never paid attention to the burner speed with CDs and didn't run into any problems.

Thanks

    Hello,

    The iMac G5 iSight came with an 8x DVD Burner. So, you can use media rated at 8x.

    Here is the technical specs for that drive:
    http://www.panasonic.com/industrial/computer/storage/optical/models/UJ846B.htm

    Now, you can also use multi-speed media that is rated at higher speeds. For example, you could use media labeled as "1x through 16x" or "Up to 16x". But, you should avoid media labeled as "16x" or "16x Only" or "not for use with drives slower than 16x". Read the small print on the back of the disk box.

    If you use Multi-Speed media as described above, then your drive will burn it at speeds up to 8x.

    If you buy single-speed media, then don't buy any that are labeled higher than 8x. Single-Speed media that is designed for faster burning than your drive supports may not burn properly (and often fails to burn successfully at all).

    As for types, DVD-R is the most compatible type. If you want the greatest compatibility with different drives and readers, then use the "-" media (DVD-R). If you will never share the disk, then use whichever you like.

    I use the minus media exclusively (DVD-R) because I frequently burn home movies for the family. And, the minus media is compatible with more players than the Plus media .


    I hope this helps.
