I have a Memorex dvd burner & I've burned about 70 dvd's on it over the past 6-months or so. A little while ago it stops recognising dvd's. cd's are no problem but as mentioned, when I put a dvd in the computor doesn't show a disc in the drive. I've uninstalled & reinstalled the drivers and still the same problem. Any suggestions? Thanks.
