Get a brand new IDE cable and hook it up by itself on IDE #2...this will tell you if it works or needs replaced.
I agree with patio but, I would try uninstalling the camera from add/remove programs and see what happens.
Did you just now add this camera?
Also,If you right click on my computer icon,then click manage,then click device manager,then double click on DVD/CD-ROM drives,does your lite-on dvdr show up there,or is it missing?
