Help Burning DVDS

sup

i just got a new computer and the program that i have that burns dvds is sonic digital media...Ive downloaded a couple of movies but cant burn them and get an error message saying "The software that is used to decode the media is not available on the system. Installing the correct decoders for the files you are working with may help to correct the problem. -47001"

Can anyone help me with the "correct" decoders or perhaps sugest a program that will allow me to burn dvds that ive downloaded off limewire??

thanks
