<pre>OK, it seems that the format is correct. HW registers also seems to be
programmed correctly. Documentation is not helpful at all, at least for me [1].
The only guess I have is that tile format produced by MFC is different than
format accepted by MIXER in regard of chroma. Unfortunately I am too busy now
to investigate it deeper. Maybe next week I will be able to consult it with sbd
more competent in the subject.
