Video deinterlacing with sopc builder

Thanks for your help, but I have found the problem:

I might seems logical, but the SOPC builder must be clocked with the pixel clock, whereas I was using a faster clock.

I'm a little bit surprised, because I thought the avalon bus needed a faster clock in order to transmit pixels and some others data in real time... and I thought that vid_clk at CVO was used to regenerate the correct video flow.

(and that's why it worked fine with frame buffer).

Thanks anyway!
