PS2 Iso's Under 700MB - CD-R Only?

Hi, everyone.I'm using Magic Slide/Swap Magic 3.6 with an original model PS2. Typically, I've obtained my PS2 discs by making direct copies from the original discs, using a combo of Any DVD and either Nero or Cyberlink Power2Go.I've downloaded a couple of PS2 games below 700MB. Can a burned PS2 game under 700mb be put on a DVD-R, or will it only work on a CD-R?Thanks in advance for the help.
