backup xbox game, disc

I have a evox modded xbox.
I know how to ftp using IE. (internet explorer)
I have the game downloaded on my xbox hard drive using the dvd to xbox software.
When I ftp I can see the folder for the game and i can access it.
how do I get the xbox game on to a disc?
The original xbox game is on my original modded xbox's hard drive and i want to play it on my non-modded 360.

what type of disc do I use?
I have a memorex dvd+r 4.7gb, will that work?

here is the picture of the disc case cover:

ok, i created the iso. but underneath source (after i selected the iso file) it says the size of the file is 4,721,410,048 bytes

my disc information says the size is 14,319,616

will that be a problem or do i need a bigger disc? where can i get a disc with that size if i need one?

 

You're right, I forgot Xbox games require Dual Layer (DVD-9) media to be burnt on to..

Get some DL media and then proceed.

 

Not all Xbox games need to be burned to DL. I burned the Family Guy game and it was only 2 gig.

 

Only original games will work on a non-modded 360.

Regardless of the fact that the game on your HDD came from an original disc, when it's burned back to a DVD-R it will be a backup, therefore requiring a modded console!
