To listen or download anything on the Beeb iPlayer overseas in Ireland and the USA etc. you need ExpatShield (or equivalent) - this fools the Beeb server(s) into thinking that you are in the UK. It assigns a UK IP address to your computer.

Then you can use get_iplayer to download Beeb video and audio progs, and RadioDwnloader to download Beeb radio progs.

RadioDownloader also handles podcasts for all sources (you don't need ExpatSheild for these). I use RD to download podcats from the NZBC, fRoots, etc.

Files shared in Mediafire should be available to anyone anyway. Its download functions are a bit clunky, and you need to accept its cookies. Its interface is based on Flash Player so you need the latest version from Adobe.

Its worth seeing what is on RadioArchive.cc - membership is free.
