dvd decrypter

after reading the dvd to my hard drive and then trying to write to a dvd/r the software tells me that my dvd has only 2.2 gb of memory and do iwant to copy it any way they are new blank 4.7gb dvd-r maybe its the fact i reformatted my hard drive to xp instead of win 98 se
but what am i missing as i used the program on 98 and had no problems,

 

Jesus is it catching today.
How can anyone help if you don't even tell us what software you are using to get this message?

Edit:
Apologies you mention it in the title (so used to lack of info from everyone else)

Are you burning with Decytpter as well? (if not the first post stands)
Have you read any guides?

 

the programs i was using were shrink and nero 6 as i put in the furom any help would be appreciated

 

So when you try and put the files into Nero it tells you that the DVD only has 2.2GB of space?
Or is something else giving you this message?
