Backup of files to DVD Image I receive 0I/O x8007045d error

While taking the backup of files to DVD Image I receive 0I/O x8007045d error, Also I will receive it while copying files from one folder to the other.
Sometimes it just freezes other times I get a blue screen and restart. Really I need help, because it's my family photos I can't back up.
The request could not be performed because of an I/O device error.
