A couple of years ago I remember seeing a camera developed by Comtrex
that was designed to take pictures off a Mac's screen. They also
provided a device to add video mixing with a second video source such
as a VCR (with the camera providing the genloc signal). While I would
love to have such a setup, what I am looking for is simply someway to
directly transfer the Mac video signal to some NTSC device. I can use
a camcorder to make pretty good copies, but there is that ever persistent
scan line to content with, as well as the difficulty of getting a
consistently good focus.
It seems to me that such a device would be fairly simple to build, but
I don't have any idea how similar the Mac video signal is to NTSC video
signals. If anybody has any info on such a device, please post or email
me. Thanks.

This may not help if you don't have a MAC II but... The MAC II allows you to convert directly to interlaced NTSC timings. An article was posted in the MAC news group giving the values to slam into the MAC II video card. I converted it to C (about 12 lines) and it worked like a charm. It provides a clean RGB analog signal. You then run this thru an RGB to NTSC encoder (available for $400) and then run this NTSC video line into your VCR or run the analog RGB into your Sony XBR and use your camcorder to film off that screen. I found it to provide glitch free video.
