In general:
Is the transfer of the cam-streams measurable ? To avoid drop-outs and to define how much room for more cameras is left to be transferred live to the same computer.
As long as the standards are 3,6 MB/sec for one SD DV stream, then 3 of these should be handled without any problems by a P4-3GHz with a RAID 0, correct ?
Is Scenalyzer able to show the transferred data per opened window ?
