Actually, it was on the ivtv list. This was the short little blurb I wrote up a couple months ago when I reverse-engineered some of the registers. I guess I didn't get any size registers, but I'm fairly certain there are some, because I remember adjusting it in that way at one point, too.
Your results may vary, make sure to back up the register maps before making changes REG: 0x6C VAL: (bits from LSB to MSB): First 3 bits - color. Normal color is 110 (rightmost digit a 6 or an E). The first bit is the "make it an ugly green" flag. I assume the other two are red and blue, but they weren't as apparent as the green was. The other 5 bits are the horizontal position, larger number is further to the right. I cranked it all the way up to get a well-located picture. ivtvctl -j reg=0x6c,val=0xFE -d/dev/video0 REG: 0x6D VAL: (LSB to MSB) first 5 bits - vertical offset (larger number is further down). The last three bits are the large adjust for the horizontal adjust. So there's a total of 8 bits of horizontal adjustment, the lower 5 bits are the low bits of 0x6C and the upper 3 bits are the upper 3 bits of 0x6C. I'd like to meet the engineers who designed this card..... I went looking for registers that would fix the color problems - I got some really weird results from a lot of them. I found some that made the picture grainy, some that made it black and white, some that made the colors REALLY bright.
