Dynamic Stream Settings

Hey ppl, since the site changed i can't find the settings for video, i have low space on C disk and i cant watch the whole on the spot anymore because firefox keeps downloading the whole damned thing to the disk, how can i set it so its a dynamic stream that doesnt download it.

I have also changed the firefox cache to the other hard drive but it didnt fix it.

is gamespot really without tech support?

I've contacted the appropriate staff to see if they have an answer for you. Thanks for your patience during this time.

Y-----yyyyeah. Anything?
