That works.

Another attempt to mount the second disc I burned was successful;
however, I'm still unable to boot from it.

At this point I'm beginning to question the reliability of this entire
package of DVD+R media.

BTW, "long" is 8 bytes on x86_64. You have to use "int" to get a 4-byte
integer type--which could be Brasero's problem. Though really one should
use a type whose size is not architecture-dependent for such a thing as
this.
