I have a problem, when I download I cannot preview and have found that the download does not match the desciption. I tried downloading one thing and got something else

You should have read the forums rules before posting names of movies, etc.https://www.gnutellaforums.com/limewire-wireshare-cross-platform/announcements.html

Try to avoid doing so; it's a big NO-NO!!!!! here
A general advice for your problem would be to use the preview function after you've downloaded around 5-10% of what you're interested in. If it ain't what you're looking for then stop the download and delete it from your incomplete list:

LW>Library>Incomplete files

sorry about that, missed that rule!! I have tried that but still get message that media player does not support the file. I have downloaded install about codecs but apparently media player doesn't support those codecs, so am having to wait ages for download to see if it is ok. because of that i am worried what may be being downloaded. am thinking of removing and not using any more. although is seems ok for audio.
Thanks for you reply.

First, do yourself a favour and "edit" your first post removing hte file names
Secondly, you could follow this link http://www.gnutellaforums.com/showthread.php?t=53593
and check on codecs; personally, I would recommend to download the VLC player, which supprots almost all. If you still have some problems to play the movie then you should check the file by clicking on it in the "search results" with a right mouse click. From there you go to "Advanced>lookup file with bitzi and check the file size and any other available info.
