6C is usually shifting to 51. It's shifting to another number when it
turns green/purple. Sometimes 6D will shift but I haven't caught what
it's shifting to yet.

Can anyone think of a way I can eliminate hardware faults as the cause
of this shifting?

Sorry in advance for the extraodiarily long post.
Here's what I've done: I've installed Linux (various flavors), myth,
and ivtv, and configured the pvr-350 tv out at least a dozen times
over the last 9 months with varying levels of success. My best
results have come from knoppmyth. Recently someone developed a very
handy perl script to get tv out working and it worked like a champ
for me (please note I was having these problems before I used this
script).
Here's what I did for my current setup: I installed knoppmyth r5a12
and got tv-out working in 20 minutes. That comes out to: Debian,
kernel 2.6.9-chw, mythtv 0.17, and ivtv0.2.0-rc3b (I've compiled and
installed several other versions of ivtv as well but couldn't get
john harvey's X driver to work so none after 0.3.2a worked). I'm
currently using 0.2.0-rc3i and would like to keep it that way because
I've recently purchased a pvr-150. One thing I've noticed from the
beginning of my foray into Linux pvrs is that when I set it up myself
the X display is always way bigger than the screen when I configure
TV-out myself. Is this adjustable by manipulating Overscan?
My goal is to be able to burn a dvd without transcoding. After
setting the recording profiles to 720x480 and with a higher bitrate
(yes I know this uses more space it's worth it for me even if it were
twice the size), I get some very odd behavior. I begin watching live
tv or a recorded program. My screen will look perfect. Great
clarity and color. OSD is centered and readable. Intermittently
while watching shows, the image with turn green/purple and/or stretch
way beyond the left side of the tv screen. Running ivtvctl -j
reg=0x6c,val=0xf5 makes it better but the OSD is way bigger than the
screen and I'm definitely loosing a lot of image (I'm considering
putting this in a cron job to run every minute). The aspect ratio
seems ok though (no apparent stretching). The problem will continue
to happen as I watch recordings or live tv, and I have to keep
running that ivtvctl command. Some times as often as every minute
sometimes not for a whole 30. I'm starting to worry that this
intermittent shifting could be a memory fault in the card's registers.
Here's some of my setup:
modules.conf (actually /etc/mythtv/modules/ivtv) snippet:
alias char-major-81 videodev
alias char-major-61 lirc_i2c
options ivtv debug=1
options tuner type=47
options msp3400 once=1 simple=1
install ivtv /sbin/modprobe tuner; /sbin/modprobe msp3400;
/sbin/modprobe saa7115; /sbin/modprobe --ignore-install ivtv;
/sbin/modprobe ivtv-fb
remove ivtv /sbin/modprobe -r --ignore-remove ivtv && /sbin/modprobe
-r saa7115 && /sbin/modprobe -r msp3400 && /sbin/modprobe -r tuner &&
/sbin/modprobe -r ivtv-fb
XF86Config-4 snippet:
Section "Device"
Identifier "Hauppauge PVR 350 iTVC15 Framebuffer"
Driver "ivtvdev"
### change fb1 to whatever number you got in the previous section
Option "fbdev" "/dev/fb1"
Option "ivtv" "/dev/fb1"
### change the busid to whatever is reported by lspci. Note that
### output of lspci is hex, so add a preceding "0x" to the BusID
BusID "0:0x8:01"
EndSection
Section "Screen"
Identifier "TV Screen"
Device "Hauppauge PVR 350 iTVC15 Framebuffer"
Monitor "NTSC Monitor"
DefaultDepth 24
DefaultFbbpp 32
Subsection "Display"
Depth 24
FbBpp 32
Modes "720x480"
EndSubsection
EndSection
I'm not sure why the script uses ivtv and fbdev in the Xconfig but
I've tried it all 3 ways with no change.
