Bought a new dvd burner, all my other burners were cds. When i use roxio or NTI to burn, it only does 2% buffer or validating, and then it just says writing, speed 0x, ive already wasted like 10 dvds by trying to do the same thing. I only plugged 2 cables into my dvd burner, nothing else. Its the SATA power and SATA data, i havent even done anything else to it... AM i missing some wires?
