I've been trying to install the 10.4.8 release with the disk util patches and everything, but each time it starts installing i.e. when I have selected everything and the installer starts to copy files. I've tried burning three different dvds and have tried installing atleast a dozen times but it freezes while copying files. It doesn;t freeze at the same position every time. What could be the problem, please help me out.
