Internet freezing on one site

[FCS tech]

I am running Ubuntu 9.04 on a laptop (Wireless) and Vista (plugged into router) on a multimedia center. I can watch tv shows from 2 out of the 3 tv network sites that i like. CTV and Global tv stream ok on both systems. however CBC won't work unless the pc is directly plugged in without the router. any ideas.

...well, a wild guess would be, that the router is blocking cbc, port/ip wise. check your router configuration.
