I have just found TVTUGA.com, a website where you can watch more than 150 TV channels, including the portuguese ones. Since I'm learning to play poker (with some friends), I can now watch the Poker channel at work (hope the boss don't read this). Well, was that or the Playboy channel...

The quality is not great, and I'm sure that in some days it will be impossible to watch any channel, just because I think the people from TVTUGA don't have the necessary bandwidth to accomodate a lot of users. Hope I'm wrong, good luck TVTUGA.
