There is a huge difference between a pro DVD type burner and a consumer level burner. The main difference is that one burns and another actually ?presses?. Retail DVDs, from hollywood, for example, press their DVDs which involves a lot of big and very expensive equipment - a pressing machine to press pits into a plastic blank DVD, a gas sublimation machine to give the pressed blank a reflective surface a bonding machine to join the layers together to make a final dual-layer disk. Again, this is an expensive option for what you want to do but you would get the perfect DVD.

With a burned DVD the information is written onto the surface of the disc simply by exposing a photo-sensitive layer (dyes), whereas with pressing, the information is physically and securely embedded in the disc.

For us mortals who can?t afford pressing there are techniques and tips to prevent authoring headaches

The first tip to remember is that the the type of DVD you purchase always matters. It may be true that the DVD errors you encounter are the results of some other factors, but always make it a point to burn DVD-R with good quality brands or purchase them from a reliable store. Tayo uden is a the best brand ? there is more about this here.

(1) Try a different media. Your DVD burner may not be compatible with your
media. To check if the media you are using is highly compatible with your
burner, please visit DVDRHELP to see what users think about the burner and media you are using.

(2) Use a slower burning speed. The slower the burning speed, the better the
burning quality. So using a lower burning speed may solve this problem.
Please check "Set write speed before burning" option in the config window.
And then before the recording process, a window will pop up for you to
choose the burning speed.

(3) Make sure the firmware of your DVD burner is up to date. Most burning
errors can be solved by updating firmware. You can download the latest
firmware from the website of your DVD burner's producer or try here.
 

What DVD authoring software you?re using can also have impact on your final burn. Your DVD authoring program should allow you to decide which MPEG encoder you use. Some DVD authoring programs, such as Apple's popular iDVD, have a built MPEG-2 encoder and you cannot use other encoders. The built-in encoders may be okay for home movies or, depending upon the software, some simple commercial projects, but they generally don't do a very good job if you want to get more than 60 minutes of video on one DVD and some, quite frankly, don't do a very good job on any length of video.

The highest quality encoding is usually "two-pass, variable bitrate (VBR)" encoding. That means the MPEG encoder goes through your video twice: on the first pass it analyzes each frame to determine how much data should be allocated to each frame, and then on the second pass it encodes it (there are VBR encoders that can do more than two passes for even higher quality).
