Basically, there are a few differences between various versions of the
PVR-350, and you have one of the ones that likes to be green (I have it
too). You'll need to do a bit of registry hacking to fix it, but it's a
very easy fix. I copied this from a post I made to the myth and ivtv list a few months (maybe a year?) back. You can probably search the archives for "350 green" and come up with dozens of posts about it, but this is the one you'll be looking for.

<br> <br>REG: 0x6C <br>VAL: (bits from LSB to MSB): First 3 bits - color. Normal color is 110 <br>(rightmost digit a 6 or an E). The first bit is the "make it an <br>ugly <b style="color: black; background-color: rgb(170, 170, 255);">
green</b>" flag. I assume the other two are red and blue, but they <br>weren't as apparent as the <b style="color: black; background-color: rgb(170, 170, 255);">green</b> was. The other 5 bits are the <br>horizontal position, larger number is further to the right. I cranked
<br>it all the way up to get a well-located picture. <br> <br>ivtvctl -j reg=0x6c,val=0xFE -d/dev/video0 <br> <br>REG: 0x6D <br>VAL: (LSB to MSB) first 5 bits - vertical offset (larger number is <br>further down). The last three bits are the large adjust for the
<br>horizontal adjust. So there's a total of 8 bits of horizontal <br>adjustment, the lower 5 bits are the low bits of 0x6C and the upper 3 <br>bits are the upper 3 bits of 0x6C. I'd like to meet the engineers who <br>designed this card.....
<br> <br>I went looking for registers that would fix the color problems - I got <br>some really weird results from a lot of them. I found some that made <br>the picture grainy, some that made it black and white, some that made
<br>the colors REALLY bright.</font></font><br></div></div>
