Panasonic BD35 into Onkyo TX-308 via WW Island 6 HDMI cable led to sound drop outs and "snowing effect" with respect to the picture. Changed to a QED Performance HDMI cable, and neither of those two issues were experienced. Have a second WW Island 6 HDMI cable to do a comparison with (to make sure the first wasn't just faulty (if that is possible)). So, to me, cable does make a difference.
