Is there a way to download Flash movies with a near 100% success rate?

Here is my problem. I recently installed Realplayer, and there is a feature to download Flash movies (Youtube, etc.). However, it seems to work on about 2/3 of the videos, while I can't download the others. Is there a way to be able to download all of them?

Hey I found that I just need to keep refreshing the pages and I am eventually able to grab every video.
