I just had the same problem, but didn't know why I couldn't burn to a DVD.  I thought the VCD would play on a DVD player, but after burning to a CD-RW discovered it wouldn't play on a DVD or another computer.  If I try uninstalling the burner what if it doesn't re-install? I didn't have to format the pc but I did have to reinstate it to factory specs for my dsl connection.  I had not looked at MyDVD prior to that so don't know if it changed, but it is supposed to be MyDVD Plus & it only says My DVD when you open it.
