this changes your answer maybe?
To get rid of those colored lines, make sure the glass under the calibration window is clean of dust or smudges. The calibration window is a small slot that is the same width as the film strip and aligned with the film strip, towards the end where the scanning head is.

About uneven brightness i don't have enough experience to say if it's processing, film not being flat when exposed, etc
