adult video script mass grabber module

hello, i reopen this project as old programmer gone no news at all. we already have a script from adultvideoscript and it has grabber module to grab video embbeded or saved it. we want to change its function to make it work automatically (using cron) grab one by one video from other site like pornhub, redtube. the video should be saved to our server not just embbed. we guess its not really hard job as the original script already built-in the grabber module, so you just need to modify it or create a side script of it. we need it to be optimized as well so the script just take a little source of cpu usage. we more prefer to those who already knows adultvideoscript code.
