Older DVD reading devices don't necessarily cope well with
consumer-writeable media. They weren't engineered for it, because the
media simply didn't exist. It's worth noting that this is not a "DVD
thing." Into the mid-90s it was entirely possible to buy a CD-ROM drive
that didn't read CD-R.

I also have an iMac DV 500 (running 10.3.2 Panther) and it has *never*
been able to read DVD-RW or DVD+RW discs from any source.

My parents claim that *their* iMac DV 500 doesn't even read DVDs. But
I'm not so sure I believe them on that one. m.

One other point. You might have better luck with DVD-R/+R instead of
the -RW/+RW you tried.

I know that back before MultiRead CD-ROM drives were common, lots of
drives could read CD-R, but very few could read CD-RW.
