That's what we're trying to tell you, if you see a file trying to connect for ages & ages, then chances are it is a fake. It's almost as though the file is there, but they have upload slots set to zero. So there's no chance of downloading it. Sure it appears in download window but that's all, you'll never actually download it if it is the classic fake file syndrome.

Best advice is to well you know about bitzi, but other than that, keep trying others till you find one that does work. And keep searching. If you are sure one of these is fake, you can try banning their ip. Though chances are they use dynamic ip's. But in the short term it will stop that particular one showing up in results from that specific source.

Trying slightly different search terms or search technique can sometimes be of help to find genuine files.
