OK, this is not the first video downloader we offer you, and that's because the quantity of programs which let you download videos from youtube and similar websites has increased a lot in a pair of months.
TubeMaster offers us some features others don't offer, and the main one is that it let us search for the videos directly in the different websites from its interface. It also lets you navigate the webs directly from its interface.
When you search for a video, it shows you a list of videos and when you click on them it also features a preview on the left side and you can reorder the list of videos by date, name, length,... Once you have selected the one you want to download, you choose if you want it as FLV, AVI or PSP&iPod compatible.
If you like video sites and you want to search and download from a lot of them, TubeMaster can be a good choice.
