Insert a recordable CD or DVD into your CD or DVD burner.
Click the Burn a CD or DVD notification that appears in Windows Media Center or, on the start screen, scroll to Tasks, and then click burn cd/dvd.
Depending on the type of recordable disc that you have inserted into the burner, on the Select Disc Format screen, click either Data CD or Data DVD, and then click Next.
Using the keyboard, enter a name for your DVD or CD, and then click Next.
On the Select Media screen, click the first type of digital media file that you want to add to the CD or DVD, and then click Next.
Click pictures that you want to add to your disc so that a check mark appears on the selected digital media file, and then click Next.
If you want to add more files to the disc, on the Review & Edit List screen, click Add More.
Repeat steps 5-7 until you have added all the digital media files to the disc that you want to burn.
After you have added all the files that you want to burn to the disc, on the Review & Edit List screen, click Burn DVD or Burn CD.
In the Initiating Copy notification, click Yes.
After the disc is burned, in the Completing Disc Creation notification, click Done
Also try putting the cd or dvd in your dvd drive then reboot then try the steps above. I am noticing that Windows Vista on my PC is not refreshing itself when i insert/take out a cd/dvd. I have to reboot first.
