Hi. Wasiii, I think I'm in the same boat as you--kind of. I have a Sony U18A that came with my computer, and using Sony DVD-R Ver. 2.0/1X-4X media to create some home DVDs. I'm using WinDVD Creator 2. I can burn a DVD with no problems, and it can be read/played by my XBox, other DVD players, and on other DVD-ROMs. Unfortunately on my Sony U18A, after it tries to read the burnt DVD, the green light constant blinks. I have no other lights on my Sony U18A, other than a green light.
So, I guess I need to know:
1) Do I have one of the Sony U18A drives that can't be reflashed? If I can reflash my drive, will I have problem when I tried to use the Recovery CD that came with my computer?
2) Will using DVD-R by a different vendor--like TDK or Memorex--resolve my problem? My Sony U18A can read files that have been burnt to the TDK and Memorex DVD-R media. These are just non-DVD files.
