15 bpp isn't a valid value for this X server.

I get this when I capture with vic also, so it may just be a driver tweak.
vic throws out this note when I turn transmit on:

vic: meteor sees no signal(1)-using ntsc.

I think you and I are virtually in the same boat, only you have an S3 and
I have a Mach64.

It is.  I have standard coax TV cable on the screw-on nub.  I don't have
any composite devices here at the moment.  I have the SVideo-out audio
patch cable connected to my GUS PnP -- haven't gotten it to put out any
audio yet.

OK, keep us posted.  I'm sure it's connected right though.

That's the thing - there's no mention of a linear frame buffer during the
X boot probe.  The Mach64 README makes no mention of a linear framebuffer
option either.

The red screen makes sense if the bits are backwards -- it's really a blue
screen.  Does tv need to select the input?

Here's the X server output:
