IE default download save location & podcasts

[megamav]

Hey guys, im sure someone here knows where to find the registry key to change the IE default download save location.

Any ideas?
I've looked around:
HKLM/SOFTWARE/Microsoft/Internet Explorer
But couldnt find anything.

BTW, any idea how I could download a podcast on this device without downloading additional software with overhead?

Right now im manually downloading the mp3 files from this page:
http://sports.espn.go.com/espnradio/...ive?id=2942325

I'd like to be able to download the new file automatically.

Thanks in advance.
