Sometimes I find a long and interesting video on youtube or vimeo about Linux events or presentations, documentaries or movies that I???d like to see in a second moment, maybe when I’m offline or from my TV that has an usb port but no wireless. There are dozen of extensions for Firefox and Chrome to do this kind of task, but today I’ve found an interesting program that can download a video from a long list of website and convert that video into another format: xVideoServiceThief
xVideoServiceThief (a.k.a xVST) is an open source tool for downloading your favourite video clips from a lot of video websites (currently supports 93 websites ) and it also provide you the ability to convert each video in themost popular formats: AVI, MPEG1, MPEG2, WMV, MP4, 3GP, MP3 file formats.
