Burning DVD's. I am trying to burn some movies I've downloaded to DVD's. First I tried using DVD

Question

I am trying to burn some movies I've downloaded to DVD's. First I tried using DVD Decrypter but as soon as I open up the program my D: drive "disappears". Not only can DVD Decrypter not see but the drive is also hidden from every other application on my computer (including Windows Explorer) until I reboot. I next tried dvdSanta. Again, the program does not see my DVD drive (but the rest of my programs continue to see it so I guess this is an improvement??). Anyway, after trying two different programs I thought perhaps this might be a Dell problem and not a problem with the burning software. Any ideas?
