how to burn a .iso file to dvd+r?

[Tristan]

ok so i got an old computer i need to fix, so i downloaded the ubuntu server.iso, and i can make a bootable pendrive from it... but the bios on the computer wont let me boot from the flash drive. So im wondering if anyone or any program that can burn the unbuntu server to a dvd+r disk (only blank disks i got now) or would it have to be a different type of disk?
