Did you know that rendering a DVD is a very sensitive operation? Your computer is constantly talking all the time and this can create jumps and skips in your finished product. Turn off the internet connection, your screen saver, anit-virus software etc while rendering! Screen saver? Really? Well think about this for a moment… how do you think your computer knows when there is no activity for the specified amount of time you requested and time to put on the screen saver? Also, when burning a DVD remember that it’s best to slow down the speed.  Optimize the video bitrate (Mbps) to about 6. (this is also a great trick to get more than 4.7 gb of information on a disc!) Also, when you put in the DVD and let’s say you have a 16X burner, burn the disc at 12X instead. Yes it takes a little longer but it will avoid discs that ultimately end up an expensive drink coasters with holes in them.
