[MacDV] DVD-R longevity

[ShirleyK]

I'd give it no more than a week if it were sitting out in the sunlight.

That reminds me. I was going to take a short video project folder to a 
meeting so I could show them how the film looked in iMovie. The folder 
was 2.5 GB. I dragged it to a DVD and let Apple make the data DVD. All 
went well (if slowly) until it failed verification. I had already used 
the same brand of media to make a regular DVD from iDVD (this on the 
1.42 G4 tower and the version of iDVD in the iLife package).

After that data DVD failed to verify, I decided to see what would 
happen if I tried to read it. It seemed to mount and I could see a 
couple of icons inside, but trying to open a folder took a long time, 
before failing.

Next I installed Toast and tried the same thing. I got exactly the same 
response from the Toast-burned DVD. Has anyone experienced this or do 
you have an idea of what went wrong? I'll try another data DVD with 
other files I want to back up and use the Apple DVD this time. But I'm 
curious about what might have gone wrong here. It shouldn't matter what 
kind of files I select, should it?
