I can make out something out of what you said Khaled. You mean to say that you create sites with videos on Mark??? Yes, you can do that with WordPress. There are tons of video plugins around to accomplish that.
If you are posting Youtube videos, then you can create a new post in HTML mode(not Visual mode). Just copy and paste the embed code given by YouTube and you can post a video.
