I just upgraded to the Liteon LH-20A1H drive and the drive does not recognize most of the DVD's that I use. I am using media from Ritek and Prodisc. Sometimes it will start burning and stop burning and after about one minute of burn time. Then it would eject to disk. I am using 1ClickDVD Pro and sometimes I use Roxio and get the same results. I upgraded from a Benq drive and no problems with any media. I have flashed the drive with the latest firmware. Any help please.
