I found this really cool online video converter for those of you who don't want to download a program for downloading videos. I tried it out and it worked really good. All you do is put the URL of the video from places like YouTube into the online converter and then choose what extension you want it to convert it to (i.e. flv.avi, wmv..etc) and about 20 or more different types of extensions to choose from, and it will convert it, and then give you the download link to save to your computer.
I knew it was just a matter of time till something like this came out, and I bet a dollar to donuts this isn't the only one. Its totally free to use and it requires no membership or anything like that. You just go their and put the URL in the place provided, and set what you want it to do, and it will do its job and offer you the download link.
