Well, you should try this one on your little DVD. I'll bet it syncs, because it's a full interlace signal. That's one of the reasons I want to further develop this TV COG. With a coupla more options, like S-video added, it should display on anything.
I've attached one that has a simple set tile method, and that does 320 pixels at 80Mhz.
And a couple of really boring screenies.
...more when I get back from my "honey do" list. I'll PM the address in a bit. I really gotta get some good tile data. I'm willing to try the VGA. The two screenies are 320 pixels and 80 pixels, just to show the tile nature, and give some idea of screen density possible.
