On a >3yr old machine with 2x Dual Core AMD Opteron(tm) Processor 270 2GHz cpus, load for live video capture and encoding mpeg4 PAL is about 50% on each of the 4 cores. >> We have a normal 4 channel bluecherry card and its worked very well >> for us.

If you're thinking about the "normal" composite capture card, make sure its the PCE express version. The ordinary PCI version doesn't have sufficient bandwidth to support 4 simultaneous full PAL size streams. Its the PV-981 which we have here. chris Christoph Willing +61 7 3365 8316 QCIF Access Grid Manager University of Queensland
