...but first off, assuming there are no watermarks on the videos, there's really no reason to ADvertize that the movies are from a pay site, right? Why make potential trouble for Alex and his crew.
That said, I would recommend experiement with a few different browsers. Some handle PHP differently than others. On OSX, safari does a great job, but mozilla's browser (firefox) doesn't give you anything but a useless little PHP file.
I assume you have windows, though, so I'll leave it to the others here to help you get movies from all those non-pay sites you want to harvest and post here.
