Um, sorry. That previous message got sent out early, by mistake. Oliver, thank you. I wanted to thank you. Also, I thought of a way to run an actual regexp on H.262 & H.264: regexp: [IPB][ -](picture|frame)|GOP|group_of_pictures H.262: 210 line-hits (no way to tally individual hits on the same lines). H.264: zero hits. --Mark.
