There are fake files around now which typically have heaps of sources, but will never connect. Search again, try the All Types search as well as Video, stay away from files with huge numbers of sources. I go for a file with 10 sources or less.

Look up files before download with Bitzi. If the file's been rated then you'll get an idea of content & quality. A file with lots of sources but no Bitzi rating is quite possibly a fake!
