Help me to modify this php script

[mrexp21]

Hello ,

I would like to modify this script a bit . It is a video upload script for my site . The php content contains all the neccessary fields and upload via browse files only . I would like to make it another optional such as remote/url upload . There have to be 2 optional uploads , whether via browse file or url upload . The php script is below : -

<?php
