Close!!

It nearly works! I could get tv-out, but the image isn't perfect yet.
what I mean is that I see it clearly, but it "jumps" a bit (as it
sounds). It is centered and you could read as in another screen. If
needed, I could record a video with my digital camera, althought the
quality isn't very good. For now, here is the result of just running
X.

Thanks a lot for your work.
