new laptop/dvd help

hello mgs,
just found your site and need some help. i just bought a used laptop with no operating system, installed a copied disk of win xp. works great, however, it did come with a non standard dvd/cd burner in the laptop. it works for software and reads cds for installing software but will not recognize dvds. any help would be appreciated. its a dell latitude c600 win xp. i tried the windows media player and it did not find anything in the drive when i had a dvd in it. it was not a dvdr but one from blocbuster. thanks for any help in advance.
johnny

 

You need the codecs like Intervideo, or another DVD player in order to get WMP to read DVD movies.
