Here we come to dinner ...
Actually now past yesterday's dinner, today's breakfast and lunch now and coming up on tonight's dinner.
But anyhow after repeatedly counting all the MPG streams comprising PIDs x05XX, x0001, x0009, x00b4, x00be, and the questionable x00f9 packets, the total aggregate stream comes to 1295.14 kbps.
Or ~1.3 mbps.
As was said, virtually nothing in the way of saving transponder bandwidth by turning off the old MPG data related streams, but perhaps a great saving on equipment resources at the broadcast center(s) by its eventual elimination.
