There are dependencies that you need to install as well. Using google next time would be a good way to start.

how? pls help me.. i am a newbie

Each link under "remember the dependencies" on the webpage I linked to is a file that can be installed. Click on each link, and say yes to all the questions during the install. Once you get through the list, things should work. If you are having trouble, the thing to do is ask for help in this thread. It is quite likely that the author lurks around there and will help you. Starting a new thread to ask for help before you've searched will you contempt from some meanies around here. You don't want to be contemned, do you??

Install mplayer in application manager.
Then videos should work in mytube
