The software is easy to install and use. It is perfect for someone like me who is quasi-computer literate. Find the video you want to download, copy the address, and open up the This software. Click on "Add Download" and the software takes over from there. It finds all the available formats, asks you to make a choice, and off you go. I can easily run four simultaneous downloads. Others automatically queue and then start when the first are completed. If you have a long series of downloads you can even go offline and say, have dinner or watch TV. The This software keeps quietly chugging along downloading the list. In case of an unexpected computer shutdown, the This software remembers its place in the download and can complete the task when restarted later. A must-have downloader for "video packrats" like me, folks with basic computer use skills.
