Can anyone tell me, when I am downloading with no problems
it stops and I get the message in the status box waiting for busy hosts then after a while the message changes to queued.
If I am downloading with no problems why does this happen and is there a way to solve this.
Regards.

This is not an individual problem. Everybody suffers this same thing. The best thing to do is to delete the file from your dwnld window(below the search pane) & reselect this file to dwnld from your search results. Try this several times if it doesn't work. Then try another search for the file over the netwk to find fresh & possibly new resources. The Gnutella netwk is very large & is connected throughout the world. People are constantly entering & leaving the netwk. This may cause a loss of connection to your file. Also, if you're dwnlding from a T1 for example, their netwk may have temporarily blocked you out. The source you were dwnlding from might be busy with other uplds also & your connection was knocked out by others attempting to connect or trying to gain a greater upld bandwidth from your source. When you go onto the busy list, it means just that, that the sources are busy & you have been put into a cue to share dwnld time with others (yes after a time you may be forced back into a cue again as those others in the same cue are rotated. There's numerous reasons why this happens & these are just a few. Hopefully & with a bit of luck you can reconnect by taking my advice or even maybe finding a new source. Good Luck.

i have thesame problem i be downloadinga video and then all of a sudden it says waiting for host and then just to awaiting sources. why does it takes so long sometimes to find sources to download videos and is there any kind of ways to make you download all these videos the sameday.

Probably because they went offline. So best answer is to see if there are any others who have same file & have available upload slots. Otherwise wait until they come back online. Put yourself in their scenario, are you willing to wait how many hours it may be needed for someone to upload a video file from you. Or will you log off just as per normal & leave it up to them to find you again another day. Personally I leave my computer on for 2-3 weeks at a time.
