OK it's definitely not Hijack. I went back to the 2.00 final kernel and it still does it.

I am now going to either go back to b13 or see if I can disable the AF stuff in the kernel somehow. I have a feeling it's all in the player software though right?

Basically it makes the one station with RDS AF unlistenable since it's retuning and causing slight drop outs about twice a second. The station is Triple J for the Aussies.
