The podcast has always downloaded S-L-O-W for me.
As an example, I'm back home and hooked up to iTunes for my podcast updates I have multiple downloads turned on.
I download Down Range Radio 120 @ 22.1Mb while it crawls along, I'm able to parallel download Gun Talk's padcast's 2009-08-09 Parts A, B, C and 2009-08-02 Parts A, B and C each
(10.2Mb, 10.2Mb, 10.3Mb - 10.3Mb, 10.2Mb and 10.2Mb respectively) And Show 120 is still not completely completed downloaded......
I'll donate a quarter for faster service - if it will help.......
