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. Regards Stuart

I seem to recall that there may be two separate lasers in some (all?) comb-units (combi-unit being one that can read/write both CD and DVD). If I'm correct then possibly the laser for DVD hath failed/died a death..;or may at least need cleaning (suitable cleaning disk kits cost a few £££/$$$ only)? http://www.cdrfaq.org/faq02.html#S2-13 The above link/reference seems to support this to some degree? as does the last contributor at this site immediately below (and the initial post there is not unsimilar to your situation?): http://en.allexperts.com/q/CD-ROMS-... This one is a general discussion on both readers and burner... http://en.wikipedia.org/wiki/Optica... If you do manage to determine what/why etc... would be useful if you were to post back here; so "we" all know for future reference?
