At least this confirms there is an issue.

I do have other hardware with with a mn88472 demod on it. A CX23102
bridge and a dibcom (Xbox one tuner). I think that running the same test
on those hardware will tell where the issue is.
I know that Olli have worked on the Xbox one tuner, do you have any
support patches that could help testing this? And did you observe any
issues with the mn88472 demod when working on the Xbox one tuner ?
I am quite sure that I saw this on the mn88473 version of this hardware
also. I just haven't had the time to test it. But I will postpone that
until the tests on the other bridges are done.
