I am a pedant me - HDV, not HD.... HD is something much better than HDV.

HDV claims to be hi def cos of a zillion pixels but lacks the bit rate to really be called HiDef. It looks ok to me on static program but the picture just falls apart on busy program. This is the main reason ( and cash) that I am sticking with pro quality sd untill I cam afford a sensibly specced HD cam - like the sony ex series.
