DVD-R on Gameshark?

[MegaPyro6]

I boot all of my backups with a gameshark v1.9. I would use a messiah but can't get a hold of one. I was wonderig if the Gameshark would boot DVD-R backed up games. I'm going to get a DVD burner soon and i want to make sure they work before i go spend the money on the burner. I know you guys recomend the A03 and A04 highly, but would any DVD-R burner work? So far my gameshark has booted everything; PS and PS2 backups, VCD, and MP3.

charlie or dust2dust can get you a messiah here.
