DVD will not read

I have Two DVD drives neither will read Plank Media or even movies from the store. They use to both work but somewere down the line settings have changed. I have even uninstalled the DVDs shut down the computer, unpluged the drives, restarted the computer, run regcure. then pluged them back in and it loaded them back in with out even telling me it found new hardware. DOES ANYONE HAVE A CLUE? here are my stats:

look for upper & lower filters in the regitery

back up before deleteing,

remove, drivers for them
remove IDE controllers for them,
reboot & try it
