Why do I get an error message saying unable to use disk when creating a DVD

Question

I have successfully burned two DVD's of a group of three I am burning of my last vacation pictures. I have successfully created WMV files for each day of the trip which I have combined to create the three DVD's so they won't be too lengthy. I created a menu with main menu and stop menu markers. When I went to burn the third disk, which is the shortest of the group the program would encode to the 96% and then the disk would eject and it would give an errow message saying the disk was not compatable. This was the same type of DVD-RW disks I used on the two successful disks. I tried redoing the burn 3  times with each time getting to 96% on the encription and then the same error message occurred. I used fresh disks each time. On the forth try I cut the number of WMV files down to 3 to make the DVD half as long. The same thing happened at the 96th% spot of the encription process. Nothing had ever been put on the disks. I am using top quality Memorex DVD-RW disks. Please let me know what else I can do. I am very frustrated. Oh yes, I closed the program down each time I got the error and also shut down and restarted the computer afer each error. I really want to finish this project as I have been working on it now for two weeks non stop. Thank you.

Good, that gets one possibility out of the way.
Since the error about the disc indicates that the Transcoding has already finished, I think that we can probably rule out the next step, but let's look anyway.
Now, for Transcoding to DVD, PrE uses 2-pass Encoding, so it would seem that this problem is comng right at the end of the second pass, at the end of the Timeline. Look very closely at that point, and see if there is anything odd there. Things like gaps in the Video of a Timeline, or sometimes Assets that are not proper, can cause Transcoding to stop. Anything there? [I think that with a disc error, Transcoding HAS completed, and the progress bar is just lagging slightly behind, but more questions are probably needed.]
Last, what brand of blank media are you using? The reason that I ask this is that some companies, like Memorex, buy the cheapest disc that day, and rebrand them, so in a spindle of 25, you might end up with blank discs by different mfgrs., and some can be much better, than others.
Good luck,
