It's Dave, actually...  My .sig is just a quote from Eolake (and is

a new .sig anyhow).

I have considered the possibility of a dead tuner...  If that is the
case, then I guess I'll just have to put 2 PVR-500s in my myth box
since I won't want it to be out of commission while waiting for an
RMA to go through.  (As if my hard drive isn't filling up too fast
with only one tuner already.)

My myth box's kernel has deprecated /proc/pci, but lspci shows both:

0000:02:08.0 Multimedia video controller: Internext Compression Inc
iTVC16 (CX23416) MPEG-2 Encoder (rev 01)
0000:02:09.0 Multimedia video controller: Internext Compression Inc
iTVC16 (CX23416) MPEG-2 Encoder (rev 01)

Something like

Brightness = -475234752
Contrast = -1054774144
Saturation = -852037632

you mean?  I was ascribing that to the card not having accepted the
commands sent by the driver to initialize it, but I see now that, if
I run ivtvctl more than once, I get different values for those three
settings each time.  That's not good...  Guess I will need to try it
on a Windows box and see what happens there.
