It burns audio cd's with no problem at all but just will not recognise dvd's when i am trying to burn them

should not take 12 hrs to burn
does it burn data cd/dvd or audio cd/dvd's ?
you might have to burn it as an ISO image
this might be because you have not selected the option to burn a dvd movie you might have selected another option ie:burn data audio or your burning software does not support movie dvd burning
there are plenty of free burning software programs on the internet

Do you have more than one CD and/or DVD player in your computer? If so, are you burning to the correct one? (You have to tell the player which). Does the CD run properly if you put music in it without trying to burn anything? Have you set the program to burn a CD and not a DVD?

Witch program do you use to burn???
