OK, Here is a per file list for the two example Proms by pid:

Useful list for me to try...
The 1280x720 examples are all with video rates around 2200 kb/s. The others
are about 1400. The audio is always 93 kb/s which is rather lower that I
might wish, but sounds enjoyable in the context of having the video.
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?

Alan
