Needing help with DVDFABGOLD

I’m trying to burn Master & Commander. First of all most of the time I go to burn a dvd I cannot burn it directly onto a DVD I have to burn it to my computer first. I’m not sure what causes it to do it sometimes and not others. So, I burn it onto my comuter and now I can’t get dvd shrink to burn it. I’m getting errors and I’ve reinstalled it 2 times now {I don’t know if dvd shrink is a program from this site or not, it was given to me by a friend}
TIA
