PS3 > Xbox 360.
Xbox cant even play netflix properly in hd how the **** do u think it will hold up on a live hd event, on a relatively new app in comparison to netflix.
It's usually fine for me. Last couple events were in HD the entire time start to finish. You can replay the event for up to 24 hours and it's always in HD then too for me.
Oh and thanks to OP, I got mine last night 30% off.
