Answer 2

Not sure how you would extract audio, but Ruby has many good scraping/mining libraries. You can use these to automate a browser and get scrape the data you need (e.g. the video embed code).

I recommend using a combination of mechanize and hpricot but here's a fairly comprehensive list:

You might also try Rio for downloading files/videos:
