Ive got my Arcam Dv79 connected to my Hs50 via hdmi and i've got a strange problem. when i connect the machine via (cr p pb dr sr vd am pb tb) or whatever it's called) I get sever vertical banding on anything the colour red. i sopose a bit like the croma bug but much more intense. If i change the setting to output RGB via hdmi the are no such problems. This happens when it outputing proggresive and interlaced. help my obi forum members, your my only hope.
