Solaris 10 clean Install failure

Downloaded Solaris 10, burned to CD, disc at once/96 and the CD was not recognised. Erased/burned disc at once, the install process started and continued about half way then froze as though caught in a loop. I attempted re-installing but it was a repeat performance!

May I suggest to use 700 Mb CD-R's and not CDRW's, as the last have less space availiable for data !
