How Do You Burn Xbox 360 Games?

i have dvd discs but they are like 4.7 gb and single layer can you use those? or do you need dual layer and bigger discs like 7-8gb? or is it possible to make the files smaller to fit on the discs?

Suggestion:

you need dual layer discs. buy verbatim discs. trust me i bought hp brand dual layer discs and i have ruined 3 already because they keep failing. i knew i should have listened to the forums and youtube videos and bought the verbatim but i figured hp was a good company with quality products. but i was sadly mistaken. you also have to flash your dvd drive. there are tons of videos that tell you how to burn 360 games. with image burn as well as clonecd. image burn is better and its not a trial like clone cd. good luck and get verbatim
