Automated script to download youtube videos to a server

Hi, i am looking for someone who can create a stable script to download videos from youtube this scrip should run on shared hosting preferly, or if need lot or resourses on a small server basicaly i need that the script do this: 1. search for customs words on new videos only, for example, a new video with the word "CAR" is uploaded in youtube 2. download the video to a folder in any format 3. create a thumbail of the video and show the title and description and also the youtube adress 4. make the video playable so i can see it 5 delete the video on the server 10 days later 6. i will add new words to search in youtube in the future, so i need to imput the new words in some place in the script ////////////////////////////////////////////////////////////////// this is an example to make more clear what i want if u click here [login to view URL];search_query=car&search_sort=video_date_uploaded u will see a list of new videos with the word car uploaded to youtube. what i want is save that videos in the server, and then deleted the videos in 10 days so i think u should make a cron job to search in youtube regulary the way the thumbs and the videos are showed should be private, and i dont care if is ugly, i dont want to create somthing to show to the public, its just for me
