anaconda is a special case because the binary rpm contains the source 
code (some of which I have included below).

Your .discinfo looks correct, comma separated list of cd numbers.  It 
may well be a different issue.  Are you still using iso9660? 
Unfortunately I don't have a DVD ROM or burner so I can't test :(


/usr/lib/anaconda/image.py looks like the place:
                         if os.access("/mnt/source/.discinfo", os.R_OK):
                             f = open("/mnt/source/.discinfo")
                             newStamp = f.readline().strip()
                                 descr = f.readline().strip()
                                 descr = None
                                 arch = f.readline().strip()
                                 arch = None
                                 discNum = getDiscNums(f.readline().strip())
                                 discNum = [ 0 ]
                             if (newStamp == timestamp and
                                 arch == _arch and
                                 needed in discNum):
                                 done = 1
                                 self.currentDisc = discNum

def getDiscNums(line):
     # get the disc numbers for this disc
     nums = line.split(",")
     discNums = []
     for num in nums:
     return discNums
