Hello All, Well, I've had this HP 300n (firmware upgraded from 300i using the 3.02 upgrade from HP) and everything was just fine until I installed a secondary DVD ROM on the same cable as slave,(in order to let the Slave read the DVD's using DVD Shrink and go directly into write on the HP)) and this seems to have been the beginning of my delima........I had to go into setup and disable the bios to recognize the two ROM's and just let my Windows 2000 Pro do the recognizing and they finally both showed in Device Manager........I have been able to burn copies of my newly purchased DVD's (mainly using TDK DVD+) and was getting excellent results (using Nero 6) until recently..now I am receiving cannot perform end of disc at once...A lot!!!!!......And also having what Nero says is a successful burn, but will not read on my stand alone DVD player (Emerson AV 111T0) where all the other burns play just fine.....I have tried Force ASPI....to no avail....and even re-installing my Windows..........But mainly, I would like to be able to read my Copies on this unit again......and what other DVD writing software should I use besides Nero : ....thanks....
