hi i just installed a pioneer dvd player in my dell 2400. Now when i first booted up 2 beeps no device found. Then i looked at it and the cable to the motheboard wasnt properly in. Fixed that booted up okay without beeps. Now, windows media player 10 needs a decoder for playing dvds i really dont want any other software. I like windows media player 10, How can i get it to play dvds? i need  a plug in or something like that. THanks!
