CVO and PAL - How?

Kevin - you are a star :)

Those values give me a nice 50Hz sync with the video starting correctly!

I see the reason why I have been going wrong. It is with the Vsync front/back porch - I thought this just defined the '6,5,5 & 5,5,4' equalisation pulses, but It appears it has a big influence over the frame timing.

The IP does not 'do' half lines so I just rounded the half lines - my field 0 vertical front porch is set to 3 and back porch to 19.

So for anyone needing the values - here is what I am now using:

(If anyone else uses these values, check they are correct for you, I have not measured all the timing yet)
