Sorry this can't help you for tonight's short programs, but you can try this out for Thursday's Ladies Long Programs. Oh, and sorry but the only places I know to access video clips is shut down to new registrations during the Olympics (to conserve bandwidth), so you may not be able to register there to download vids until next week.
Though they do require registration to access the videos, Figure Skating Videos (
http://fsvids.9.forumer.com/ ) is a great resource for downloading vids from recent events and even some classic skaters and skating documentary fluff. They should open back up to new registrations within a week.
AFAIK, RussianTVOnline.com, China's CCTV-5, a German TV station and a few others will be streaming live. You can Google the Chinese site, but the German TV site's link to the live streaming page is
http://www.zdf.de/ZDFmediathek/inhalt/12/0,4070,2397068-5,00.html (supposedly Mac friendly if you need). Eurosport only has a live *audio* feed, though their commentators are quite amusing!
Hope this helps! Good luck...
