I'm here to second the notion of reviving this thread. I would also add that I use the cdburn.exe from the Win2k3 Server resource kit which is freely available to all for download. Once the resource kit is loaded or the file is extracted, it could be put in the path or called from the HFTOOLS directory. In any case Tomcat76's suggestion of using NOBURNISO and BURNISOCMD to control the burning application means any utility that takes a command line will work. Just for the record the usage for cdburn.exe if very simple and limited, and is surprisingly fast. It also outputs a percentage display as it burns and supports erasing prior to a burn for RW media. C:\HFSLIP>cdburn Usage: cdburn <drive> -erase [image [options]] cdburn <drive> image [options] Options: -erase Erases the disk before burning (valid for R/W only) -sao Writes the image out in "session at once", or cue sheet, mode (default is "track at once") -speed Speed of burn, or 'max' for maximum speed -imagehaspostgap Use if your image already contains a 150 sector postgap The [image] must be provided unless the -erase flag is set. If both an image and -erase are provided, the media will be erased prior to burning the image to the disc.
