I have 2 dvd drives. One is a burner (Lite-ON ,Max. 20xRw). Another one is just a DVD-Rom drive(Read at 24x). The problem is..... When I burn a movie into 16x DVD+/-R media, my dvd-rom drive won't recognize it (playback). Although I reduce the writing speed of my burner to 8x or even 4x on 16x DVD+/-R media. However, it works on my dvd-player (the one that burns with 8x and 4x), but somehow not on my dvd-rom drive. So I tried different dvd+/-r media, which is 8x DVD+R media. It works on both my dvd-player and dvd-rom drive. Is there any way to fix the problem? What's wrong with my dvd-rom drive? Any suggestion? Since on the market today, 16x DVD+/-R media is everywhere. It's hard to find 8x DVD+/-R media on bestbuy, officemax..etc.
