I searched for this, but counldn't find the answer. When song 1 is playing in player A, and I load song 2 into player B, the video in player A cuts out for a brief second and then returns. The audio remains continous. We are using the most recently available version downloadable from the web site of both Scratch Live and Video-SL.

Windows XP, very well optimized using hints from this forum
Core 2 6600 CPU (2x 2.40GHz)
3.25 GB Ram
NVidia GeForce 7600 GS

Any ideas?
