MEMRI may have a suspect agenda with its founders and I don't imagine they should be expected to give a balanced account of politics in the Arab world.
Nevertheless they compile many videos, largely broadcasted on Al-Jazeera, worth looking at. See links in this blog entry. You will probably need a broadband connection to view the video clips. There are particularly interesting and disturbing videos on a recent Iranian anti-Semitic exhibition about the holocaust here [1] and here [2].
A recent video is the speech of Hamas Prime Minister Haniya. It has been cut and spliced but nevertheless I think it gives a flavour of Hamas's policies and their populism. See here [3]
