You should go to the main page of the show you wish to view.
On that page you can determine whether episodes and/or clips are available.
In the episode list look to your right.
To see a full selection click on 'more episodes' or 'more clips'
(DO NOT click on an episode title in the listing.)
This will then display a 'pictured menu' of videos available.
double click on the one you want to view.
If it does not play for you, you should see an error message telling you why it has not played.
Hope that helps. If still stuck message me.
At the top of each page (under the sharetv logo) there are 5 links. Click on watch online. Scroll to the bottom of the page and you'll find a scroll bar with a list of available shows. Choose the show you want. This will take you to a page with episodes available for that show. Choose an episode and click play.
Bear in mind that currently only members from the us can view these shows. That said some members have been able to view them using an ip sheild. Read this thread for more information:
