258230 Looking for a Scrape / Crawler

I am looking for a simple script that will scrape or crawl 4 specific video tube websites and that will take the title description tags embed code thumb time length every 15 minutes, half hour or hour, which ever I choose and post it to my database on my Video Tube website. I use clipshare so anyone that is familar with it and think they can do it please contact me. I would like the script to run itself on the server. I dont really know how it would work. Maybe I would be able to choose which of the 4 sites that day I would like to scrape from. Or maybe rotate and take from each site ever 15 or 30 minutes. I just want to be able to have a new video posted every 15 or 30 minutes automatically all day rather than me manually having to go and get one and post one everytime. However you think this can be accomplished and the best way just let me know. And if you have any other ideas to add please get back to me. Thanks.
