I know there are DVD test discs out there that have test patterns on them.

This would actually be fairly trivial for me to whip up on my computer. I
just did a quick google search and the first hit had a downloadable GIF
of the standard color bar pattern. I could toss a 1 MHz tone (IIRC that
is the right freq, I'll have to look it up to be sure) in the background,
and loop it in Quicktime, then output to VCD.

If you really want one, let me know, I can build you a VCD this weekend
and mail you a copy.
