Acer Recovery disc

Hello, ive been trying for a few days to burn off the default settings for my acer aspire 5738Z but. i am unable to .... everytime i attempt to burn an error comes up with both the factory settings and drivers..... i tired to burn with both cds and dvds and both failed and i've already tried using the burner with both so i know it's not the burner malfunctioning...........so i was wondering if there were special dvds or cds that are to be used or if i should just contact the company or is there an alternate method by which i can attain the settings..........
hoping for a speedy reply,
Dar
