Ah! Again, thank you BurninMan
A little more insight into the NeroVision burning problem: It appears the program is only burning the main menu and none of the videos. On a DVD+RW test i just did, the menu popped up just fine, but one of the links started playing a portion of a video previously encoded on the disc (i used quick erase on the RW). Most of the links just crashed the player.
This data should have been overwritten with something, even if it were garbage, had NeroVision completed the burn process. The previous movie took up a small amount of the disc and the one i attempted to burn would have nearly filled it.
Overall, I am dissapointed in Nero. In my attempt to find a quick solution to turning DivX files into DVD's NeroVision has proven it cant transcode correctly (audio synch problems, sometimes severe), cant burn reliably (the above mentioned issue), and costs a hell of a lot more than other programs.
