I had it working at one stage without audio, I think something has

It turns out that I needed to modprobe wm8775 alone prior to inserting
ivtv.  If I do this first most tuner combinations work for both
NTSC/PAL & cardtypes 1&2.  I have noted a firmware lock-up when using
cardtype=2 from a fresh start.

I can recover from this by reinserting ivtv using cardtype=1.
Cardtype=2 can also produce ivtv: i2c client addr: 0x40 & 0x21 not
found! errors (still works though?)
When using cardtype=1 I get... i2c_adapter i2c-0: I2C level transfers
not supported
&  cx25840: I2C write failed, length 3, ret -38 (again it still works)

Cheers & thanks again,

Lew
