This was a fairly common problem in the early days of DVD readers and questionable DVD media. My main computer could read the disk fine, so I created an .ISO image with ImgBurn and then re-wrote it to a new disk. My controller had no problem reading that disk and I was up and running quickly, which was lucky since I didn't have a spare DVD drive handy.
I learn that trick a couple months ago when I needed to use the Tormach recovery disk after a hard drive failure. Same issue - I could read the disk but not boot from it.
