I also tested the oldest of the minimal installer ISOs [2] still available, also without success. For both my rx4640 and rx2660 I get the following output when trying to boot from the internal DVD (its access LED lights up shortly):

Last time i used it, Brasero didn't have an option to verify the just burned disk, you likely have a bad burn.  I always use k3b for just this reason, i.e. the option to verify the just burned disk.  This is particularly important for any install dvd as a corrupted dvd is a fine way to get a corrupted os.  The fact that other dvd media works for you suggest strongly that it's a problem with the dvd.  try again and make sure to verify the burn, even if the disk can check itself it's entirely possible to have burn errors that produce a correct checksum.  i've had just that happen with an update i downloaded and had to download 4 times to get  a correct version, the first 3 check summed correctly but had the same defect.




Dvd burns frequently go wrong, with my current media/burner they fail 5-10% of the time so far and that's typical in my experiance (though the age of my hardware is doubtless also part of such issues).  If it's important, verify the burn, i always do even if it's not code, and absolutely always, always with os install media, just too many opportunities for bizarre unreproducable problems if a couple of bits are wrong.
