Great AZO4*dvd+r blanks dont work

i have two machines with dvd burners. one is an sony vaio one is an e machine with a digital resreach burner. they both work but for some reason they will not work with the great AZO dvd +r blanks they both ± burners i check for firmware on digatal research site no firmware. the sony i update the firmware one time. any help would be great thanks :eek:

Great AZO are low-end discs. Don’t be fooled by the claims that these are the same as the Singapour made Verbatims.

thanks for the info.
