short answer - no. You cant view video embedded websites like sky player on the device. I would also recommend that you DO NOT update to the latest firmware because Youtube has problems once you have done this.
IS sony internet tv any good at all? since it appears the only usefull apps are Facebook, twitter, skype and youtube.... so can we expect any decent apps in the near future or is it better to just buy an idiously ugly looking samsung instead?
and No, connecting a pc to your tv is not a typical 2012 solution
