I have a large ISO file, over 1GB. Ok, so i have dvd/combo drive , and i was thinking i needed a larger blank cd file to burn the large 1GB file. SO i bought a DVD+R disc, from sony and my dvd/combo drive doesnt read the disc. I mean, i put the disc in, it loads up a bit( green light flashing ), but i dont see it in the D:\ section??????????? What do i do to burn this file, do i need to install a dvd problem or something?
