omg DONT LISTEN TO ANYBODY ELSE
ONLY USE VERBATIM DISC. THEY CREAT HIGHEST QUALITY MEDIA AND FOR AN EXTRA 3p PER DISC ITS WORTH IT
apologies for caps but 324 is a "read error" and as a read error its just a problem with reading the disc nothing to do with software or hardware.
what u have experienced is a "bad burn" happens at times.
on imgburn select in the speed menu "AWS" this will automatically slow down or speed up burning to decrease chances of bad burn.
to solve it simply burn the game again.
