I've got a problem with VLC and live (streaming) in the Zaurus-SLC3100.

Live uses a handler to manage the sockets it uses. While I push the
sockets into the handler there is no problem. But when I try to get them
I can't because live tries to access to fReadHandlers but its OID is
different to the one used to push the sockets into.

Could it be a bug in the application? What Can I do?
