So, are you saying that:
* magiclantern-Nightly.2015Mar02.5D3113.zip (e8cc6e5) is buggy? (has pink frames?)
* magiclantern-Nightly.2015Feb20.5D3113.zip (36ff475) is fine? (as in, can you throw a lot of abuse at it without getting pink frames?)
If - and only if - the answer to both questions is a solid "yes", can you check this mlv_rec.mo on any of the two builds? (ML core is identical in both).
It should display "Last update: df0bbfe" when you press Q in the module dialog, and it's the only intermediate version between the two builds.
If - and only if - the modified mlv_rec.mo works fine, and you can say it with a solid "yes", can you try it (modified mlv_rec.mo) on a recent 1.1.3 nightly?
Hey Alex,
Just spent a good few hours testing. The results are in!
Test:
Record 16 clips, camera settings as follows... 50p, 1920 16:9, MLV Snd enabled and ON, GD ON, Focus Peaking ON, Histogram ON.
Rack focus during recordings to liven up the focus peaking.
Review clips in MLRawViewer at 23.976 stretched to 16:9.
Clips that have 1 or more bad frames marked as BAD.

PASSYOU'RE THE MAN A1EX!!! IT WORKS!!! 
This intermediate mlv_rec module produces no bad frames on the latest April 1st nightly, also records past the 40gb mark.. My camera is currently rolling next to me and has hit the 11 min mark at 24p.. Well past 40gb.
Question is, what does this all mean? What's the difference in the 'intermediate' mlv_rec module VS the mlv_rec in the 2015march02 nightly?
And also where does this leave 1.2.3?
Thanks so much for your time and efforts.
