All the reviews regarding the Panasonic TX-26LXD70 LCD TV indicate that it supports 24fps, however I have justed purchased a Panasonic DMP-BD30 Blu-ray player which supports 24fps and connected it to my TX-26LXD70 via a 'CHORD HDMI' 1.3 Silver Plus' cable, and I am unable to turn on the BD-Video 24p Output setting (this option is greyed out). Can anyone help?
