I've noticed that when using mlv_lite.mo (Raw video v1.1 (MLV Lite)) with FPS override FastTV mode, when recording RAW in 1x crop mode on 5D mark II, it will contain intermittent backward frames.
Watch this https://youtu.be/m1_FBnhzXCs There are 2 backward frames in this sample sequence, they are marked and should be easy to notice.
Here is the source MLV : https://goo.gl/txLJoN
The sequence will contain more backward frames with slower shutter speed, for example FPS override of 15fps and shutter speed of 1/17s will produce about 20+ backward frames scattered randomly in a 2000 frames sequence.
However, the same settings works correctly with mlv_rec.mo (Raw video v2.0(MLV))
Hopefully this could be fixed. Thanks!
