Thanks to another poster - turning off Chil Lock allowed PIP to work as described in the manual
I have an LA40A650 LCD TV. I have HDMI1 connected to a Beyonwiz PVR and this works fine. I can also watch digital channels on the TV source, being the in-built tuner. I think this should allow PIP to work (Main picture HDMI1, sub picture TV). However, when I go to the Setup menu, PIP is greyed out.
Should this work with my setup? If so, what am I doing wrong?
