Nero 6.6StartSmart

I use DVDshrink and burn it to a DVD using Nero, but when it’s finished encoding, then goes to burn. It says a error or something, I’m really not sure except that it doesnt work. When I save the DVD file after it finsishes shrinking, I open NeroStartSmart to burn the DVD file, but then it says there’s a power error. Can someone tell me if i can use some other program or try doing it a different way??? I would really like your help. Please and Thank you
