The same thing happens to me with Juice. Because I always remove the extra characters from the file name, I just re-downloaded "It Was Death By a Bullet" (chosen for the short download time) and reproduce the resulting filename herewith:
EPFlash_ItWasDeathByABullet_nvb_20090327201645_nva_20090328202645_t_0f82b44e5034ac407a767.mp3
In my case, the extra characters aren't all gibberish - I recognize, for instance, today's date (but not the download time, in any time zone, unless there's one that off by ten minutes ... or the server's clock is) after the letters 'nvb', and for some reason, tomorrow's date after the letters 'nva'. The stuff after 't'
is gibberish.
Also, unlike mentioned by the original poster, the extra characters are added before the extension.
Not all of the (few) feeds I get do this - the CBC feeds don't, nor SFFAudio or Start Cooking - but Escape Pod, Podcastle and (possibly significantly, since it's not an Escape Artists feed) Decoder Ring Theatre all do.
Also, it happens on at least two different computers connecting independently (i.e.
not both at work or both at home, through common firewalls).
I've Googled a bit about this - a bit desultorily, I'll admit - and haven't been able to find anyone else mention the phenomenon. Whether that's because it's not out there, or because my (usually adequate) search skills haven't been able to find it, I can't tell.
If anyone has any insight into this, if not an actual solution, I'd love to hear about it.
But, if I unsubscribe, won't you lot all disappear?
