I've got the following devices connected to a Panasonic TH42PX70:- PVR on Scart AV1. PS3 on HDMI 1. I was surprised to find that if I'm watching Freeview via AV1, and switch on the PS3, the active input is not switched to the HDMI port. I have to manually select it using the AV button on the remote. It's not a big deal, but is there some way of enabling auto-switching when using the PS3? My understanding is that auto-switching is only possible with Panasonic equipment - correct?
