Your "Blu Ray player" appears to be an Audio Video Receiver (AVR) with a built-in blu-ray player. It is a component of a Home Theatre in a box or HTIB, which usually implies limitations on quality and flexibilty.
The intent is that you connect the TV to to the AVR and that connection should suffice. Any other video sources (game, cable box, etc) should be connected to the AVR.
Should I get rid of the optical and use the hdmi with arc for audio, or should I get rid of the arc, use hdmi only for video and optical for audio? I watch a lot of tv, meaning much of the time I will be watching standard tv channels.I also want to play xbox 360 and seemovies from usb connected to bluray player.And ofc watch bluray movies from bluray disks.I currently use HDMI to output the video from bluray and I use optical to get audio from tv and xbox.What do you suggest?
The obvious weakness in this setup is the fact that your AVR appears to have no spare video inputs and only very limited inputs for audio.
To use your Xbox you thus need to hook its video link directly to the TV. You have the option of hooking Xbox sound to the AVR via either analog or digital. I would favor using the digital connection if possible.
You shouldn't need to attach the TV to the AVR via any other means than HDMI, but you need a HDMI cable that supports ARC. Under your situation, ARC may be your best option for watching over-the-air TV.
Your basic problem is the limited functions offered by your HTIB.
What problems are you encountering due to reliance on the ARC connection to your TV?
