At present we can't. The magnet links they offer are for other p2p networks & aren't compatible with LW unfortunately. But you can use all the other info provided to help you such as alternative names the file is known under. Searching these names will help you find the file or find other sources to the file.

(Those magnet links are not only incompatible but out of date! Bitzi needs a kick in the shins to get their act together about that. lol )
