Hello everyone. I have a Philips 42PFL5405H. Until now I had connected a Yamaha HC to HDMI1 (ARC one) so when I play a a movie from USB everything goes well as the sound is passthrough the revicer which decoces Dolby Digital(as you should know the tv can't passthrough DTS). Now I have bought a HTPC that I want to connect to the Yamaha reciver using HDMI so the receiver would decode the audio and passthrough the video to the TV. The problem is that when I try to add the new device in the menu of the TV the HDMI1 connector seems disabled and when you select it, it says that there's another device using that connector and it's already added to the menu. If I connect the reciver to the other HDMI everything goes right, but I would like to use the ARC connector so I can use receiver with tv shows.
Sorry for a so long post, I would like to thank you your efforts in advance.
