New-want to burn dvdrom games. need advice.

[darth mickey]

Hello--
Thanks for reading and hopefully helping me out.
i have a modded ps2 and gameshark 1.6. i burn my own cdrom games and am now looking to burn my own dvdrom games. i don't like having things ripped from the dvdrom games so that won't do it for me. i know i'll need a dvdrom for the computer. but do i need to buy a dvd-r writer, or a dvd burner? is there a difference? on ebay dvd burners are going from 300-1200 dollars, so there must be some difference. my goal is to burn a dvdrom game, then just stick it in my ps2 with no switch tricks. Possible? if not, i heard i can do switch tricks with GS v1.7/1.9. if someone could give me some help--remember, i'm new so i might not know all the lingo--i'd appreciate it. thanks for your time
