I don't think the magnet links at bitzi work ... or are out of date for Gnutella users. The links might work for the other networks. But as suggested, Bitzi is very good for checking to see if there's any reports about the file you're after. It will also help you to see if the file is known by any other names. I haven't tried the ones at peerweb, but they do suggest 'most' of 'their' links are for Gnutella2 which is not the same as LW uses. Similar story at bitzi.
