Flash / Mpg4 video downloader and importer.

Hi, I want a program which will basically crawl through a site, that lets you stream videos (its a paid site i have an account for). And download the videos as well as the titles and descriptions to my PC. The program should download all of that data. Streams are available in flash of mpg4 (there is an iphone interface). The program should go through downloading bit by bit. I will basically keep the program running all the time to download pretty much all videos, but would like to be able to type in things not to download, and things to download. Eg. Download "Simpsons", but don't download "7PM Project". I can provide the site on request (only one site to get from). However it is done, i would like it to limit speed, so it does not become visible that i am downloading the streams, i want it to look like i am just streaming and watching lots of video, but then that video is saved on my pc (or NAS) as well as the titles, descriptions of the show so that i can import it all into Windows Media Centre / Player. (If you can embed descriptions of the show into the file, it would be great but if not thats okay). Low budget, not more than 150USD but 100USD is much better :). Thanks,
