There's the encode/decode time which isn't that big of a deal - just fractions of a second. Also, most likely the HD broadcast was going through some sort of set top box that buffers and adds a second or so of delay more. My tivo adds about 2 seconds to the same feed without the tivo. The path from HD truck to your TV goes through a surprising array of boxes that can also each throw some delay in there. Likely though, it's just the DVR/STB at the end putting in the most delay.
