Can\'t read Dvd, just with Nero Showtime (Optiarc AD-7200S)

[qanda]This thread is about the Optiarc AD-7200S. Click here to see full specs[/qanda]I have a Dvd that is only recognized with Nero Showtime. I want to convert to a Mpg/Avi/Wmv file(s) but can’t found a way

None of this products recognize the Dvd: Windows Media Center, Windows Media Player, Classic Media Player, KMPlayer, AVS DvdPlayer, Dvd X Player, Blaze Media Pro, ConvertXtoDvd, DivX, Vlc, Dvd Decrpter

Yes, maybe the Dvd is not proper burn or was not closed but no matter, can’t get another Dvd, must be this… Nero Showtime opens it, so… must be a way

Any idea folks :confused:
