Detailed Description

a utub search.

utub makes the search quite difficult, as an individual token, the movies unique url, is needed to stream the clip. those are not included in the search result page itself, and can only be obtained by parsing the single movie player pages.

so after parsing the search result, we use multithreaded subfetching to parse utub's movie pages, to obtain a token for every movie there.

Returns:

an imagefield of movies
