I am trying to write to a CD-R disc from ITUNES to my driver which is a Matshita DVDRAM UJ-851S and its does a couple of songs and then I get an Itunes error that says " The attempt to bun a disc failed. An unknown error occurred 4251" Do I need to update my driver and if so, where do I go to do that? I have a HP Pavillion DV9000
First of all, please try to slow down the burning speed iTunes uses to burn the discs (You should find this in the settings/preferences panel).
Make also sure that you use a CD-R, not RW disc. There might be a problem with not empty or well-erased RW-discs so with a CD-R you are safe :-)
If this still doesn't help, you should check for a newer iTunes version and maybe try another CD brand.
If you are using Windows, you can also try to deactivate all virus scanners for the time burning. There is also a Microsoft helppage to solve burning problems caused by Windows:
