Best way to capture video/audio of the PCjr

Hi,
What's the best way to capture video/audio of the PCjr?
Ideally it should capture the RGBI output and not the composite one... I have a (cheap?) composite-to-usb capture device and I see everything black & white (although it captures with color in the c64).
As a backup plan, does anyone have already a working setup to capture video? I'm coding a program and I'll need to do a video capture of it in a few weeks... could anyone do the capture for me in case I can't have my setup working ?
Thanks!

I get a B&W picture on everything I've plugged into the composite output on my PCjr. I've tried with older & newer flatscreens, a composite to VGA adapter, and also a composite to usb capture device. My C64, TI99, and 800XL all put out a good color picture on these devices...

good to know I'm not the only one seeing everything in B&W.
it seems that the color-burst is being ignored... perhaps it is using some "old-spec" a newer devices don't recognize it ???.
In any case, if anyone is able to capture vidoe in color (and would like to do me a favor), and I would really appreciate it. Thanks!

The ideal way to capture video from CGA, PCjr., Tandy or 200-line EGA would be to use a GCLabs digital RGBI to analog RGB converter, then an Open Source Scan Converter and finally an HDMI capture card capable of at least 720p/60fps.

I guess I'll need an adapter from "PCjr video out" to db9... right ? any idea where can I find one? or the lines that I should connect ? (schematic).
Thanks!

You have a technical reference manual, right? If not I can post a scan for you ... but the pinout is in there.

IBM came out with an official adapter that converted the pins from the BERG-style row headers to a standard DE-9 female for the IBM 5153 PC Color Display and similar monitors.

thanks for the info. I don't have one, so I'll try to build one myself.

Embarrassing, but is there any good samaritan willing to capture the video output of program (a demo) that I did for the PCjr ?
I'm going to present it this weekend in a party, but I've just realized that I don't have all the needed components to do the capture.
I have 3 of the required 4. I already have texeleco, GGlabs and GBS 8200... but now I need something to capture from VGA.
The only thing that I can offer in exchange, is to add this good samaritan in the greetings section of the demo.
Many thanks!!
