Hello Col,

I may be way off the mark but, going by the black bar near the top of the raster, which could be the field blanking interval, it looks to me as though the frame timebase might be running at half its normal rate, that is 25 fields per second instead of 50! Perhaps you could try adjusting the field hold control to see if the black bar can be eliminated, thereby showing a single frame, instead of what appears to be two fields one above the other, albeit with the top one extremely compressed vertically?

Regards,

Dave.
