It says that the CD/DVD must first be initialized (formatted), just like magnetic media (disk, diskette) do.
We have DLA (also 5.2.0) on our computers, but haven't used it. Instead we use the (Sonic-supplied) IBM RecordNow, which came pre-installed.
Sonic has a
page that has some Q&A's. There is no indication that I can find that the (-R) media are unacceptable.
You say that you are "trying to save pics on a dvd-r". Two questions about your computer:
1. Can you verify that the optical drive that you have can
record on DVD? Some drives are Combo drives, that only
read DVDs, and read and write CDs.
2. It is possible, although unlikely, that your drive is limited to the DVD+ (not DVD-) media.
To learn more than you ever wanted to know about DVD, see
here.
You also ask "what kind of cds do i need?" The answer is: whatever the drive will support. Again, there are CD- and CD+ media. For CD-related info, see
here.
