Apologies for appearing to be asking specifically yourself - and for my 
poor phrasing. My opening remarks were addressed to you but then a 
miscellany of musings fell from my brain to the keyboard.

I'd mentioned them possibly being OT as I hadn't been considering the 
fetching of podcasts via GiP but by direct download and was wondering 
about the SR difference between a directly-downloaded podcast and the 
mp3 file with which one ends up if downloading the broadcast program via 
GiP. The one I had just looked at was R4's Friday Night Comedy:

Yes, I guess the argument applies here also. I'd remembered Shoutcast 
compatibility being given as a reason for 44.1 still being evident and 
also remember mention of The Archers as being a special case because of 
their sound effects library but I hadn't expected podcasts to be 44.1 
and can't picture where 'podcast generation' takes place in the chain. 
That "open.live" part of the URL may provide some sort of clue 
suggesting linkage with live radio.

Podcasts usually/often have an intro and outro to identify the 
series/brand with a 'topped & tailed' version of the programme and 
sometimes elements cut out - presumably because of rights issues as 
those elements often seem to include music.

As I'd said, not really GiP-related but just something that had struck me.
