hello db3
There's two options to videos. Those on the Gnutella network & torrents.
(1) Gnutella network: searches are limited to span how far they can reach, so using the Get/Find More Results option is good because it helps to reach further (use it 5-15 mins after search has finished). Also using slightly different search terms on occasions. Different times or days may find different results. Search the video title on Bitzi, you may discover the video is titled differently sometimes, has alternative names.
(2) Torrents: use a web search engine like Google, type in video title & put torrent after it. You may find what you are seeking.
