Do I have any options for recording output from a jit.gl.render without rendering to the CPU?

That is, it seems to me that all options I have available necessitate a render to matrix. Is that correct?

I have an older Macbook Pro that isn't doing anything, and I wouldn't mind recording to it, but that seems to cause similar problems - if I use jit.qt.videout to output to firewire (which I believe my old Macbook could record as if a firewire camera were hooked up, i.e. without additional hardware/software purchases), then (again), I have to render to matrix.

There's nothing that will allow me to treat the firewire port as a display output, is there? This would allow me to send the jit.window destination of the jit.gl.render to that second display, and output to firewire while still keeping it all GPU-side.

Use a capture card and take the DVI out, its best quality and lowest CPU usage for use with 2 machines, but it means spending cash.

Anything going out of the DV port needs to hit the main memory on the CPU side. You could try jit.gl.asyncread, but it may not be fast enough for you, I don't know. You could also try a screen capture app, newer apps can work miracles and are very good, even at high res.

Check this thread out for capture card info:

AFAIK this is not possible. You will either have to use some kind of screen capture software (i.e. FRAPS, Snapz, Camtasia) on your host system, or come up with an external hardware recording system.

There are also many people working with non-realtime mode to capture from the GPU - this is essentially equivalent to rendering. Search the forum if you're interested in this.

Is there any consensus on screen capture apps and which to try?

Hmmm, maybe I'll give IShowU a try. Cheers, guys.

you can also try the render node by Randy Jones : 

i didn't test it but it seems it could help you.
