Ok, I copied and pasted the post below after be directed here by baldand.
"Hi,
First off, I'm so very happy to have this convenient software.

Previously, I had 1.2.3 and was having problems with it skipping when trying to view mlv files. I now upgraded to 1.4.1 and it's doing the same thing. I am shooting at 24fps with 1/48 shutter on my 7d (Nightly). I'm also getting vertical black banding and was hoping someone knew of a way to get rid of this.
Everything seems to play 24fps after exporting and into FCPX, but was wondering if I need to change a setting within MlRawViewer so I can view the footage without stutter and what can be done about the banding.
I'm kind of desperate here. Any help would be greatly appreciated."
*A screenshot won't adequately show the banding, so I will attempt to describe it better. It's like a horizontal shadow moving up the screen when the clip is playing...almost like when you would get bad reception with old TV's while adjusting the rabbit ears. It starts at the bottom and then moving up the screen. It's only on a few dark clips.
Also, is there anything to be done about the skipping while trying to view footage?
Thanks for the response!
