www.cadenaser.com is a good radio feed (click the "Escuchar" link in the top left corner of their page), but it is in Spanish... They broadcast during all Liga matches (for al teams) as well as Champions League, Copa del Rey etc...
There used to be quite a few TV streams online, but over the past year or so, many have stopped working, and even the ones that do work are too slow and do too much buffering to be effective.
My advice would be to find a bar/restaurant that will show the matches live (but they might be on too late at night where you live, right?)
Hey R10Deus, I've found this link in our forum: http://people.freenet.de/yoshi7/stacje.html
( can't rememner who posted it, maybe zyad?)
CCTV5: a Chinese sport channel, can see all Barca matches, Chinese commentator
Super Sport Gold and Super Sport SA: English ones, less links than CCTV5
UBC Star Sports & UBS SS Gold: English, too, less links
Other channels: never seen before
Yea, the Madrid and Zaragoza game links I found from CCTV, but it's hard to watch with all that buffering going on. Most of those are Asian or South African, and being from California, the connection isn't so great. I haven't really tried lately but maybe I should give it a shot again.
