Go to the Watch Dragon Ball fan site. A link can be found below in the Resources section.
Find an episode you want to watch. The episodes are in order and numbered, so it will be relatively easy to find the episode you want.
Click on the episode you want to watch. This will lead you to a page with two embedded videos. One is from Megavideo and the other is from 123video.nl.
Select which video you would prefer to watch. Both offer fairly good quality, but Megavideo will generally stream better for American audiences. However, it also has a limit of 70 minutes that can be watched before it forces you wait an hour to watch anything else.
