HELP - Do i use DVD's on all backups

[5thcav]

Yes i have the CD's? why,,, i didnt know i could copy them?

but i knew i could download them, like i said im new,,,

will they record in dvd format on a cdr if the image/bin has the format?

can a ps2 read a cdr? or just dvd's some of them are under 700meg and others are 1 to 2 gig,, i know i need a dvd for those

thanks
