i have problems to download videos. even when there are 100 hosts who have what i want, limewire keeps telling me, it needs more sources.

i don't have the same problem with music

and oh, i have the mac version for os 10.3. but that shouldn't be the problem, it used to work fine before.

please help!

There are heaps of fake files throughout the network & these will sit connecting for ages & then get stuck needing sources forever. Check out the threads below for info & tips. Make sure to use Bitzi to check files before download...if a file has lots of sources but no Bitzi rating, chances are it's a fake
