The problem is when you apply the video reset it also resets registers. On
which input does this problem occur? You would probably need different
settings for it.
I'm using the regular composite input (the mpc622 does not have a tuner).

Hey everyone,
After 3 months of troubleshooting my PVR-500 MCE D492, I have
finally been able to receive a signal (great video, great sound)!
Before, I had the frequently brought up problem of static that would
fade to a black or dark red on both turners. I finally found my
answer here:
http://www.gossamer-threads.com/lists/ivtv/devel/20065#20584
First off - Chris said to try not using a driver after 0.3.2t for the
PVR-500 MCE... so, I'm using .0.3.2s.
In that case, I think I know what change broke it, because exactly
between 0.3.2s and 0.3.2t, color in PAL video broke for the Yuan MPC622.
(Sorry for the chopped lines, thunderbird doesn't do what I want).
Basically, putting the video reset back (around line 1142 in
cx25840-driver.c) in fixed PAL color on the Yuan MPC622. Nothing in the
changelog mentions its disappearance, so I guess nobody knows why they
were removed between 0.3.2s and 0.3.2t.

Edit the driver/cx25840-driver.c file and change the line (L66 for me):
static int no_black_magic = 0;
to
static int no_black_magic = 1;
Then, save and recompile.
For some reason, just having this in the modules.conf file wasn't
enough. Here's my settings for that (I also have 2 PVR-250s):
alias char-major-81 videodev
alias char-major-81-0 ivtv
alias char-major-81-1 ivtv
alias char-major-81-2 ivtv
alias char-major-81-3 ivtv
options cx25840 no_black_magic=1
options ivtv ivtv_debug=1 tuner=8,8,57,57
And, that's basically all she wrote! I really hope this helps some
people out because I couldn't figure it out without the help of Mike
Benoit.
Thanks!
Matt
