Many websites and web browser add-ons exist to download a video from the video-sharing website YouTube and save it to the computer in the FLV (Flash) format. FLV videos can’t be played on many mobile devices, which means that downloading a video in the FLV format means you need an Internet connection to watch YouTube videos, as well as a computer. Download YouTube videos in the MPEG-4 (MP4) format and you can transfer them to and view them on portable players such as iPods. Tips Writer Bio
