When I record using Raw Video - Magic Lantern on my Canon 5D Mark III the video have some vertical stripes like this: http://postimg.org/image/axn6evtup/
how can I fix?

More light, higher ISOs (don´t exceed 1600 if possible), open the stop more, overexpose a bit.  MLrawviewer has a "debanding" function that eliminates this "fixed pattern" noise a bit, but it will never completely go away. In dark areas or underexposed parts of the images you´ll always see it a bit if viewed too bright (or in log mode before grading).

What build are you using? I was just testing a few and I found Nightly.2015Mar16.5D3123 had terrible banding issues.
