dvd backup on ps2?

[funcolady]

Is anyone out there reading this aware of a way to rip a dvd into a format that can be burned onto a cdr and played on a ps2? since there are ways to play backup copies of games on a ps2, i would guess there should be a way to play dvds that way too. any help or ideas?
or just any way to play a backup copy of a dvd on a dvd player without ownind a dvd burner......
