So I came across something truly odd.
I ordered a couple of those "DVD on demand" things - you know, where they basically burn you discs of older content on demand, to avoid having to have many of them pressed, due to small demand.
Anyway, looking at the disc, it's pretty obvious it was burned in a computer and not pressed in a factory. The bottom is a purplish color like any DVD-R or DVD+R I've used. The label also looks like it was printed with an inkjet printer.
But I put it in my computer, and ImgBurn says that it's encrypted with CSS encryption - and it also has RCE protection, locked to region 1. I was trying to figure out what this disc was composed of, and can't really come up with anything.
ImgBurn shows:
If I try to make an ISO anyway, it immediately fails:
I could totally understand a disc being encrypted if it was a factory made disc, but I've never seen this on a burned one before. Is there any way I can get more info about this disc, like what type of media it was, etc.
Has anyone ever heard of such a thing?
What I also find odd is that when I put it in my computer, it takes about 30 seconds to read the disc before it finally shows that I inserted a disc. Usually that happens right away with anything else. Weird, huh?
--Edit--
Oh, here's the info in the right panel of ImgBurn, if that helps anything.
