Looking closer, yeah, for some reason my logic (which is the required procedure to start a capture safely by the cx23416 chip) in the /DECODER_ENABLE_OUTPUT ioctl in the cx25480 driver was changed to do a reset of the chip instead (which only on enable too). It needs to turn the output on/off, just like the saa7115 procedure does, it's a needed function by the cx23416 chip and something that for some reason was altered (and the new code makes it harder to do that simple task, I need to add more raw register access for that procedure to be done right). This is what resets all the settings, gets them off kilter from the shadow register cache values we expect the chip to have, and undoes settings we have set.
I'm digging deeper, basically go into that function (which also has the black magic parameter in it, not exactly the place to setup the tuner??), and comment it's actions out, then at least it won't reset your config every capture.
