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.
Jelle.

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
