Synching mpeg means usually shows up for one of two reasons:
1. The server is full and can't accept any connections.
2. The server is down.
There has been a vunerability discovered recently in the SC server software that allowed (rather easily) for someone to crash the server. Someome might have just decided to take take them out.
It could be any of the three scenarios, but it's definately one of the three. If you connect to their server at the SC status panel address (you'll find it in the playlist on Winamp when trying to connect - it looks like http://184.108.40.206:8000
) see if any things shows up. If it doesn't they're down. If it does, server is full.
