Thanks for all the feedback.

OK, after a lot of testing and looking through logs I finally  
accidently stumbled on the problem. It seems to be a HW fault on my  
B4. Perhaps a dry solder joint, cracked pcb or camera component not  
seated correctly. If I squeeze the right side of the screen, just  
below the camera lense, Record-55 starts displaying the video image,  
sometimes blank, sometimes green/purple, sometimes back to normal.  
Managed to successfully recorded a video clip while the image was good.

I'm reasonably handy with a soldering iron so I'll open up the unit  
and see if I can see the specific cause. Is there a specific place I  
should report this HW issue incase it is more than single an unlucky  
occurrence?
