PD170 Jumping Picture Problem

I was shooting a show last night with a PD170 locked off and clamped to a solid structure.
On reviewing the footage today I am seeing lots of shifts in the image, where the picture "jumps" about 10 pixels up and to the left, moves slowly back to centre, and then "jumps" the same distance down and to the right.

The camera was set to manual focus, 1/50th shutter speed, auto iris with custom preset limiting to 6dB gain. Steadyshot was on.

If anyone can suggest what's going on here I'd be grateful!

I've posted a short clip to show this. It happens close to the beginning and close to the end.
I've messed with the contrast to show this clearly.

Quicktime: http://www.morreaux.co.uk/video/jumpy_PD170.mov
WMV: http://www.morreaux.co.uk/video/jumpy_PD170.wmv

They're 1.8 MB files. Only 280 frames long, but full resolution so may take a minute to stream. Probably quicker to right click, download, play from computer.

Thanks in anticipation for any insight.
