I can't seem to find any information on the resolution or frequency of the HDMI signal from the new Sky box.

I ask because I am looking at HDMI capture cards and one says it only accepts 1080/24 as would come from a BD player, but not 1080/50 or 60. I would guess that what passes for high definition from Sky would most likely be 1080i or 720p, but I can't find anything that actually says so.
