Once you find a way to do it, it probably always works. But for the beginner, I only tried sporadically to view their TV, and I always got problems. Some mirror site would be down, or freeze-framing, and when I got anything, it would be innocuous stories about nothing.
Now, suddenly it's easy.
The non-TV stuff was also usually impossible in the early war years, but in the last couple years (Obama?) has become easy to read. But the slant is usually the same as AP, so why bother (probably because a lot of the articles are from mainstream American or Israeli sources).
Anyway, to discuss the future instead of the past--Next time the US fights a war in the Middle East, you'll have problems getting Al-Jazeera. You can't win a war unless you control the media. The propaganda war is part of the game.
