PC CD drives can't read DC disks because the DC disks are written in such a way that the laser (in your drive that reads CDs) can't move close enough to interpret the data. In other words, If you're trying to play a DC game on your PC (through Chankast, of course) using the DC disks (non-burned, but actually bought), it won't work. Your PC can't read the disk. If you want to play it on Chankast, you're going to need to download the CD image from some site, somewhere. Try searching on
http://www.google.com it helped me.
Hope that helps clarify things somewhat. And no, you PC will never be able to read a commercial DC disk. It's a hardware issue, not an emulation issue. Mouser X out.
