Considering you are not supposed to know how your system works and these files are hidden by the operating system, I hesitate to describe this any better for security reasons. But Cloudstaker did understand and gives a reasonable description as to how to do it.
I think these are two different requirements. In the URL reference, the person is trying to 're-play' previously played media, which is contained in a file... yes, 'hidden' for some value of 'hidden'...
However, I think this user is asking how one would 'capture' essentially a live streaming Internet radio station, for later replay, or for controlled start and stop so they can let the 'foreign' language sink in.
I have the same problem with german radio stations, but have not really looked into how to capture the real time feed, or perhaps 'syphon' off the feed into a local file for later replay.
When I was in Germany in November I bought a number of Region 2 DVDs in PAL format, turned off any 'auto' starting of the standard player widgets, and I'm able to play the DVD's via VLC, and even better, enable the German closed captioning so I can not only 'hear' the german dialog, I can read the German closed caption.
This sort of thing is not available on most DVD's that have been imported and re-mastered for the US market.
I'm sure the same is doable for french products as well...
But back to the syphon... would that not just be a matter of setting up a script to bring in the real time feed, and then output it in some standard audio format to a file?
