And I can tell you that a Voodoo 3000 with TV-out works.

I hacked the bt869 driver to support 720x576 output.  What chip does the
ATI card use to make the interlaced video?  Would this bt869 driver help
you?

On the other hand, I could not get anywhere with driving a TV with the
Matrox G450 - as you know, the TV out isn't supported.  And the G550 tv
out isn't supported either.  So - to go Matrox you need to find a G400.

Incidentally - there is another approach to TV output from PCs - which is
to drive the TV directly with PAL-rate interlaced output from the VGA
card.  This can be done with a simple VGA->SCART cable with few or even no
active components.  And a TV with an RGB-input SCART.

However- I couldn't find a video card that would support all of:

 - interlaced display
 - low enough pixel clock to drive pal scan rate at 720-ish horizontal
   pixels (13.5MHz or so I think I remember)
 - XVideo

If you are prepared to use -vo x11 then perhaps an older vga card would
allow this approach.  But you'll need a strong CPU etc.
