I am having a similar problem, which many others are complaining about. I too am getting tired of the excuse of packet writing software supposedly being unreliable. I used Nero for a couple of years with no problems what-so-ever, so if they are claiming unreliability, they are referring to D2D, not all packet writing software.
I purchased EMC9 because I like the program better than the new Nero, but I am having problems with D2D rebooting the computer in the middle of copying a large number of files (around 1800 files with 1.7 gig of space). Windows will then tell you it recovered from a serious error. I have also found that if you stop the copying process part way through, then restart it to copy the rest of the files, it will work. The program seems to be caching the files, since, if it crashes, there usually won't be any files on the disk at all. If you stop the copying process, and restart it, all the files are written to the disk. All of the functions of EMC9 work with the exception of D2D. I've tried, by using msconfig, rebooting with nothing running in the system tray with the exception of D2D, and still have the problem. I'm using the same disks I used successfully with Nero. I also have the latest firmware for the drive. I only have the problem with DVD+RW disks, CD-RW disks work fine. Creator works well with –R and +R disks. I want to use the D2D for backups using my backup program, so I need a reliable packet writing program. If I need to use Nero to write to the disks, I might as well use the Nero program.
I am used to purchasing products from companies whose tech support responds in a timely fashion. Roxio, Sonic, or whatever they are called this week, will respond if and when they get around to it. If they have an unreliable product they should admit it and give the customer the option of going somewhere reliable. Apparently, since several people are having the same problems with this software, there is an issue with it that tech support should address, rather than using the reliablity excuse.
