I've read what there is to read about the Green/Purple issue but I don't think my problem is similar.

I was working fine for a couple days before this happened. WAF went up to about 95% since we weren't getting the lockups while skipping ahead anymore. I've been messing with my alsa drivers and may have hosed them but I hadn't done anything in a day when, while watching a show the screen shifted to the left with a blue line on the right side of the image followed by black. I tried shifting the image over using the frontend appearance settings but it would just dissapear into the blue line.

I rebooted and it came up fine (after removing ALSA from the rc.5 startup directory since I broke it and it froze the boot process). After a few minutes the screen shifted to the right this time and turned green and purple. This happened several times, sometimes switching to green and purple sometimes not. Sometimes shifting to the left some times to the right. Some times it stays the way it is for a while, some times it keeps changing.

I've tried running ivtvctl with several setting from different posts I've read. I can get the colors back and move it around (no idea how to do this with any accuracy) but I can never get it back to normal. Nothing's coming up on the logs. Here's some vitals let me know what else I should post.

not sure which version of firmare I'm using but I updated it about 2 months ago.

The WAF is around 50% now and dropping every time this happens. Help me Jebus!

Not sure but it could be a heat problem. I have the case totally open in the middle of my living room so the CPU is running at 25C. The Hauppauge is incredibly hot. If I had to guess I'd say well over 70C. I'm gonna get an IR thermometer. I'll post results later tonight.

might also be that I'm using fbdev and ivtv at the same time in XF86Config-4:
Code:
        Option          "fbdev" "/dev/fb1"
        Option          "ivtv" "/dev/fb1"


I'll comment out ivtv tonight and test

Tried going back to just using fbdev: total x lock-up. No crash, no log info. It just hung using 98% of the cpu. Switched to just ivtv. Seemed to work but after a couple hours the image shifted left without the color change. I'm sure it'll give me color change sooner or later. Sears was out of thier infrared thermometers :(

I've resolved this by upgrading to a new version of ivtv. Anything above 0.3.2b doesn't work because of John Harvey's new ivtvdev X driver so I'm using 0.3.2a. I'm sure there's just a change I need to make to the X config to get it to work and since I'll be getting a pvr-150 any day now and will probably need newer drivers to get it to work. I'll post results as I get them.

UPDATE: this did not fix the problem after all. Just didn't reoccur for 24 hours.

ivtv0.3.2a does not appear to be working either. I got a screen shift tongight then my recording went all wonky withhorizontal lines of various color (quite pretty actually). I'll post when I find a stable driver or determine that my card is toast.

Could be a firmware issue
Could be related to the fact that my record and live tv resolution is set to 720x480.

Still no response from ivtv-devel, or mythtv-users. I've tried several versions of the firmware and about 13 different IVTV drivers. I've gotten the new ivtvdev drivers working by changing the BusID line in XF86Config-4 to BusID "PCI:1:8:0" None of this has worked.

I've been able to determine that the decoder registers 6c, 6d, and 6e are randomly shifting. I can correct these problems by manually resetting these registers, in fact I've written a script to reset them every 5 seconds. This is tollerable only as a temporary band-aid. It seems like this is a hardware issue, as I can't imagine a reason for the driver to be randomly changing these values. Here are my findings so far:
Code:
Register   Orig-Val   Shifted-Val   Result
6c         f9         51            Image shifts to the left
6c         f9         00            Image turns green/purple
6d         00         unknown       Image shifts down
6e         90         50            Image turns completely black


I've emailed hauppauge, but I'm not holding my breath. I'll probably just buy a new one and return the old one.

I've built a temperature controlled fan system, and shoved the thermistor into the heatsink of the 350. It's pretty sweet, because everytime I access mythbackend I can hear the fans ramp up slightly if the room is quiet. Long story short this has apparently fixed the problem. All smiles from this end.

UPDATE: This was not the cure. I recently went back to ivtv 0.2.0j and within 20 minutes started getting register shifting again. So, somewhere between 0.2.0j and 0.3.4s something was changed to eliminate the shifting. I'm going to figure out which version of ivtvdev is causing the problem.

ivtvdev(xserver) updates:
0.3.4s (not yet implemented in the 0.2.0 branch)
0.3.2b 0.2.0-rc3d (not working until 0.2.0-rc3f)
0.3.1d 0.2.0-rc2h

I know I was getting no register shifting with the previous ivtvdev so I'll find which version, I'm guessing the change problem will occur with anything between 0.3.1d and 0.3.4s because I had a long stretch of problems that were fixed after 0.3.4s. I'm having other problems in 0.3.4s so I'll probably end up trying an older ivtv driver with a newer xserver driver. I'll report my findings as they come.

IVTVDEV was not causing the problem. I went back to 0.2.0j with the newer version of IVTVDEV and still got the shifting. I upgraded to 0.3.5z and all is well. Thanks for everyone replying to this thread, it was much appreciated.

This is still unresolved but happening less frequently after installing large case fans controlled by the heat of the 350 heat sink using a thermistor and mosfet. I'm pretty sure heat is the issue, causing memory failures in the PVR-350 registers. Oh well. I probably permanently damaged it when I closed the case and put it in an unventilated cabinet. My suggestion to anyone having similar oddities: send the card back if it's still under warrantee.
