Yeah I found CDCheck that will compare files, pretty cool.
But now my problem is with an ISO file I have. DeepBurner only burn 363MB of it instead of 4GB. Don't know what's wrong.
I tried BackupMyFiles that works with a rightclick over a files or directory and when I tried with the ISO it prompted my if I wanted to burn the image of the ISO or the file itself. Unfortunatly, BackupMyFiles does not support RW medias.
Well, I think I will install Nero that comes with the drive. Forgot this was included in the box.
Keep suggestions coming, may serve those who bought OEM package.
