Well that was interesting.

It turns out that I was loading the ivtv module with a parameter of
"tuner=57" I can't quite remember where that came from, but it was the
cause of all my problems.

From dmesg...
tuner: type set to 57 (Philips FQ1236A MK4) by ivtv i2c driver #0
Apparently this is an NTSC tuner.

If I just load the ivtv module with no tuner= line, it autodetects this:
tuner: type set to 38 (Philips PAL/SECAM multi (FM1216ME MK3)) by ivtv i2c
driver #0

I've now got better quality image on all channels except ATV, and prime is
in colour and TV One has sound.

I'm happy now :)

When I first got my PVR-150 I put all sorts of parameters for the module
with very mixed results (all the parameters were mentioned in various
howtos). However just oading the module with no parameters and allowing
auto detection to do its thing solved all my problems.

Same here - most of the online guides that suggest all the different
no_black_magic and suchlike parameters were for versions of ivtv way older
than the current generation. Just modprobing it with no parameters picks
both my 150s up no problem now.
