I recently bought a 451 and have burnt a few DVD's and a CD on it. The DVD's work fine in my RCA DVD player, and the Cd works fine in the 451.
Tonight I made the drive an 851, all is fine and it is burning fine, the discs still play in the RCA. However when I try to read the discs in my Liteon LTD-163 it acts as if no disc have been inserted even the CD. Everything else works fine in this drive.
I have not updated the firmware since I bought but have never needed to.
Any suggestions on why it is not detecting the new discs I am making.
