Got magenta casting on DNG, anyone know how to fix it in post

[lonestar]

I shoot MLV on 5d2, after I transfer to DNG, every frame has a magenta cast, I know some one already post this issue, but is there a way to fix this in the post, I tried Davinci, lightroom, they are all difficult to fix this easily, I have a lot of footage, now they are all with this problem, anyone knows how to deal with this, please let me know, thanks a lot.
