Lay the ribs on the top rack of the grill (away from the coals, if you're using briquettes). Reduce gas heat to low, close lid, and leave undisturbed for 1 hour. Do not lift the lid at all. Brush ribs with barbecue sauce, and grill an additional 5 minutes.
You can store about 27 hours and 30 minutes of video on a 64gb memory card.
@ Entropy, 2 hours on a 16GB card that costs from 80 to 100 dollars is just riduculous to me, I want a decent looking video, but I'm not filming a wedding or anything. Really, I just want as much video time for each MB as possible without quality suffering too, too bad.
