Watching videos on Youtube, DailyMotion or other video sharing websites is a great pastime. However sometimes your favorite videos are removed and you lose them forever.

If you want to avoid this, the best option is using an online video downloader like TubeMaster. This easy tool works with the most popular video sharing sites such as Youtube, DailyMotion, Metacafe, MySpace and others, enabling you to download videos as you watch them. The program downloads videos in FLV, but features a built-in tool to convert them to other formats right on the spot.

TubeMaster doesn't require any installation and works great. One thing I didn't like though is the downloading process, which is a bit confusing. If you click on the "Media download and conversion" tab you'll see a list with the videos that the program has captured, but they won't be really saved to your computer unless you click on the Save button. This is obviously also a necessary step if you want to convert it to other formats. Conversion works fine, though it would have been nice to have a small progress bar instead of just a "Converting" sign that gives you no clue about how the conversion is going.

Despite some minor flaws, TubeMaster is a great tool with which you can browse, download and convert videos from the most popular video sharing sites.
