I am using BENQ 4x DVD+R 4.7MB disks with Nero Burning Rom 6.3. I am not able to set the burn speed below the maximum speed of 4x when burning. I have been having a problem with the edge of the disk getting corrupted on some writes and was wondering if anyone else has had this problem and has solved it. I have tried using Nero InfoTool and it will not let me set the burn below 4x or 8x depending on the media. If I use a 8x DVDR then I have the option of 4x or 8x but I would like to burn at 1x.
