windows xp -os x leopard anonymizers?

[Toprak]

since youtube is banned in turkey, i use anonymizers to watch youtube, on my mac (intel) both windows xp and os x 10.5.4 are installed. when i start up in windows, i can watch the videos through anonymizer sites such as ktunnel and ninjaproxy. however, on os x, those sites will open the page but wont load the video. i tried using different browsers such as safari and firefox 3. no difference. is there a way to set this up? adobe flash does work on other video sites that are not banned.
