Oh boy another d56a question..please help



Guys, please I beg for your help. I have a new i2200 dell laptop . it came with a dr±d56a slim dvd burner. I downloaded the pd7 firmware but I cant get it to burn any dvd which will not play on my home dvd player.

originally when I would burn a movie it would skip in the beginning sometimes but after I upgraded everything didnt play. my verbatim datalife plus blanks dont read either.any suggestions?
