Hi, I also own a 400Mhz Mercury with 384MB of RAM and, indeed, the video performance is weak. Anything Flash based, like YouTube videos, slows down the machine heavily. But if you switch the color depth from Millions to Thousands you will be able to get a better performance out of the video system. Try it, you'll be able to watch youtube videos this way.
