Hmm

Do you mean that this is error occurs if the system calculates that the total stream requirements are too high? In other words, it's a protective issue rather than an actual detected error condition?

I'm a little surprised, since my setup was only trying to run the cameras at 320x240, with a reduced frame-rate (15fpm) and reasonable compression (30).

Do you know if it uses the MAX throughput requirements, or the limited throughput based on the Camera's current settings?

The reason I ask is that I would think that two 320x240 streams would have less throughput requirements than a single 640x480 stream.

I guess I need to do a super limited test.

Phil.
