a couple of newbie questions

[Adam12]

I used to back up games for my DC and am just now getting back into console games (have been stuck in MMO's for too long).
I read the sticky on commonly asked questions and was unable to find answers to these questions. Also if I missed it just tell me im stupid and to read it again, I know how annoying it is when pople dont bother to read stickys and dont know what the search feature does.

can I put one of my games in my dvd reader and a blank dvd r in my dvd recorder and simply hit copy? Is it that easy? After I have a mod chip installed of course. I understand unlike the DC I will not be able to play backups with out a modchip
if so are games often bigger then the max size of dvd r's (4.7gb)

Thanks in advance for any help
