Jake thanks for you reply,

The only clue I have is that the data is More currupted in the first part of the frame (field 1). While field two is currupted but still visible.

Basicaly the Buffer writes one 720 * 243 Frame, then the read part reads the buffer twice ( to make up field one and two 720*486)

As during field 1 Both Read and Write are acessing the memmory controller, i am assuming it is some sort of arbitration problem.

What do u think?

thanking you,
