Hi and many thanks.  I recall reading some of that in the list but at 
the time I was still happy with flash and didn't take it in.  I am a 
little wiser thanks to you.
It all seems very subjective however and whilst I understand the higher 
frame rate might be better for action material it might not be optimal 
for A History of Art in Three Colours and similar documentaries.  I 
shall have to experiment a bit.

On a good day with both lines working I can get 5MB/s.   I wonder what 
will happen when we move to 4K?
Thanks again,
Budge
