TubeSock grabs YouTube videos from the web and copies them to your video iPod, Mac, or PlayStation Portable. TubeSock knows how to convert the video using the codecs and bitrates best for each device. It can even add the video to iTunes for you.

TubeSock can play back YouTube videos directly. Just copy & paste the YouTube URL, and TubeSock will play the video for you. Click "Save" to save the video to your computer or iPod. TubeSock converts YouTube's native FLV file format into H.264, MP4, or MP3 files.

It automatically determines the appropriate file format, bitrate, and naming convention for the selected target device. Don't have a video iPod? That's OK, we don't either. For luddites like us, TubeSock can grab just the audio portion of a track and add it to iTunes, too. Find your favorite tracks, outtakes, and live recordings on YouTube, then click "Save" to copy them to your iPod. YouTube already uses MP3 for audio, so the conversion is quick and there's no loss of audio fidelity.

TubeSock can install a bookmark script for your favorite web browser. When you browse to a YouTube video you like, simply click the bookmark button. The video will instantly appear in TubeSock.

Don't have an iPod at all? TubeSock can save videos into your Mac's Movies folder, so that they can be played full-screen with FrontRow and your Apple Remote.
