Hi,
I recently re-formatted my HDD, and re-installed windows. 
After re-installing all my drivers, I cannot use my DVD burner device (NEC dvd_rw ND-4551A) as a DVD device - it does not read dvd files 
movies OR files
PLEASE HELP… 
Thanks
You probably had an app like PowerDVD installed before, and have just neglected to reinstall it. Windows Media Player (WMP) will not play DVD’s. You need a program specificly for that. I’m pretty sure Media Player Classic will play your DVD files, and it’s free. Get it here:

Hope that helps.
