Stuttering, unusable video MLV - 5D III

[McCoffeeee]

Hi all!
I recently upgraded from a 5D II to a 5D III
I was using MLV Raw on the Mark II and loved it but after installing ML on the Mark III I've had nothing but trouble

Setup: I've tried all these cards with the same results across all.
5D III
Lexar CF 128GB 1066x (160MB/s)
Lexar CF 64GB 800x (120MB/s)
SanDisk Ultra 64GB (100MB/s)

The resulting video when converted to .MOV (Prores 422, 422HQ or 4444) is stuttery and choppy, maybe 4-8Fps

Resolutions tested:
1920x1080 - Unusable due to skipped frames
ML complains the 80MB/s files will result in dropped frames on the Lexar 1066x

Dropping resolution to 1600x900
-> ML says continous recording is available
Same choppy results as before.

Any clues as to what may be causing this? Error with camera card writer perhaps?

Firmware version in use?
Exact ML version info, please! Help tab -> Bottom screen.

Are you using MLV_REC or MLV_Lite? Please give as much details about settings as possible. Esp. fps override option.
It would be helpful to get an unprocessed sample. Please share! And a processed sample, too.

Tools used to convert MLV to mov? Version?
Players used for replay? You tried different computers and players?
