|I have 3 DVD decoders which previously worked well.|
Now, none will detect that a DVD is in the D:\ drive.
Double clicking the drive in 'My Computer' with a DVD loaded results in "Please insert a disk into Drive D:".
Data and Audio CD's are no problem.
In Add/Remove Hardware, Media Control Devices, Legacy Video Capture Devices and Video Codecs all check out as "This device is working properly".
So why has my system stopped detecting DVD's?
Any suggestions appreciated.
