[AG-TECH] Audio and Video Syncronization

I was watching a session today closely, and am seeing very tight synch 
between audio and video. This is with audio on a Linux box with an 
ES1370-based PCI128 card, and video on an Athlon win2k box..

I suspect again your problem is some combination of some network loss, 
causing rat to increase its buffering, and the use of the SB Live, which 
induces higher latency anyway due to a large fragement size.

We should do some testing online sometime, and see if others are also 
seeing the badness.
