I don't fully understand what it is that you want to do, but I'll suppose that you want each video to play at the same position on the particular page. You may want a "lightbox" effect for this: the page is darkened and a little window opens for the video at its center. There are many explanations on the web of how to do this, and most of these are more or less incoherent or otherwise poor. A
good example is the splendidly no-nonsense one by Saeid Mohadjer
here, which you should read together with the explanation linked at its foot.
To embed videos that start automatically when they appear, see for example "
JW Player for Flash" (which isn't only for Flash); see its "autostart" option.
You can link to these videos as you wish, e.g. from each of a number of list items.
