Picture in picture is faster than TV screen? Answered
I was just watching the Blackhawks win the Stanley Cup (woo), and my dad turned on picture in picture so we could see what another channel was broadcasting, but as a default it started on the same channel. The weird thing was the picture in picture was a full 1-2 seconds ahead (the audio was synched correctly with the main picture). It's an HDTV connected to a cable box.
This is pretty much the least important question ever, but I found it weird and wondered if anyone had any ideas.
