Hello I have a nice Plextor 740 with the latest firmware and it writes DVDs with no problem but recently I have started using dvd+r dl media and I am getting these "Session Fixation Errors" one of every two discs. I know its not a memory problem and i dont think its the dvd writer because it does write perfectly on DVDs. Also I am using Verbatim DVD+R DL discs made in singapore.. Any help will be appreciated
