I'm trying to encode and burn my first DVD

using DVD decrypter, but the directions from the guide say you must have a DVD that is under 4,718,592,000 bytes, but there are few DVD's now a day that are that size. Can some one give advice on how I can practice and be proficient at burning with these bench marks? I hope I get some good feed back, my other questions have been answered with some irritation, but I'm sure some of you remember what being a newbie was like. Thank you

Thanks 

Thanks allot, I will try it
