Just wondering what it is that determines how low of a speed you can write a dvd at. I'm using a Lite-On SOHW-812S with the latest firmware, and can only burn at 8x,6x or 4x. I was hoping to get down to 1x as these dvd's aren't playing properly on some dvd players. With my Plextor 708A at home, I had this problem with burning at 4x (i think. at least that anyway). The video was choppy in some parts, but I was able to burn at 1x with dvd decryptor and it played fine. Using these memorex dvd-r's at the moment. Using Nero Info tool, it says they can be burnt at 4,6,or 8x. But is that because of the drive or the disc ? Thanks.
