Hp iq504 all in one

I have a new ip504 and it will read CD and DVD. It will write CD but not DVD. Says burn failed. Any ideas before I take it back to hp?

What brand of blank DVDs are you attempting to burn ?

Have you tried using quality blanks like Verbatim / TY / Sony ?

Try a moderate burn speed 8x - 10x - 12x

Hope this helps.
