Im after a script which can crawl video sites like youtube, dailymotion, metacafe etc and it will show thumbnails of their video clips on my site. So if I choose it to crawl youtube's recent videos it can crawl that category and the results will show up on my site.
Users are able to watch the videos directly from my site. The videos themselves are not downloaded onto my site but are streamed via youtube etc.
I'd like the script to be able to crawl automatically - daily or twice daily.
I would prefer a working demo, however a script from scratch is ok.
