If you will take a second and try to understand the answers you've been given, you will have a better grasp on the problem facing you. Gratuitous sarcasm will net you very little.
DVD drives have a type of built-in software....it is called firmware in the drive and is contained in a rom chip. The firmware determines how the drive recognizes blank media, and sets the burning strategy for each type of disk. Media that has been introduced since your drive's firmware was released will not be recognized properly, and thus the drive will resort to using a generic burning strategy, and most likely will give you poor results, or even failed burns with newer media.
Your best course of action, if you want to use this particular drive, would be to obtain some Taiyo Yuden 8x blank disks. These are the closest thing to universally accepted disks that are available. If you are in the US, you can buy them online at sites like Rima.com or Supermediastore.com. If you are in Europe, they are not as easily found.
I would advise trying to update the firmware, but your drive is so old, this would be pointless. Firmware updates usually stop within a year or so of manufacture.
The other options would be to try Verbatim 8x (if you can find it), or Verbatim 16x disks. Verbatim makes good quality media, but the 16x media would still be a crapshoot with a drive this old.
You can also simply get a newer drive. DVD burners are relatively inexpensive these days. Once you have compatible media for whichever drive you use, you can burn video onto a dvd. If the format is not supported by your stand alone dvd player, you might have to convert it however. Some players can handle avi files encoded with xvid or divx, many cannot. All will be able to play dvd-video, so that is a safe choice as a conversion target.
AVStoDVD is a free conversion program that gives excellent results, if it turns out you need to convert your videos.
