Keepvid is an excellent program for YouTube! Extremely easy. All you do is copy the URL from the page you are viewing video, paste it into www.keepvid.com, and it creates file you can then save to desktop. To take it to an even further step, you can save a bunch on your computer and then burn them to DVD; therefore, saving space on your system. You can use a very good, and FREE program called DVDFlick. I copied all the episodes of Biggest Loser Australia and burned them to DVD using the program and it worked perfectly. Just remember though, since the files are coming from a web site, the pixelation is different than on television. Basically, you will see the same quality video on your television as your computer after burning.
