Hmmm, this doesn't sound great. When you say you're getting no sound from the 2nd player, do you see the synchronisation icon at all (instead of the rather naff radio one - all submissions welcomed)? If so, I'd imagine it's failing to auto-synchronise the two players.

I found a problem with the sync code the other day. I've fixed this in the latest version I'm busy testing, but still needs some tweaking. I've can send you this if you don't mind being a guinea pig.

Cheers
