Useful list for me to try...

Actually the issue of video bitrates is something else that's had me 
puzzled. I was comparing some downloaded programmes from BBC Four 
recently to decide which to save for archiving purposes. As you're 
probably aware, sometimes programme series are repeated maybe a year or 
so down the line. In a number of cases I found that two programmes with 
the same --pid were of different size and on further investigation I 
found that although they had the same video rates (1280x720) they had 
vastly different video bitrates as you have described here. I wonder why 
that would be so, is it determined at the "transmitting" end or was it 
an issue of me accessing a different server?
