Thanks again for the guidance. I feel like I am getting close to resolving the issue. From what I can tell, I should take the following steps:
1. Connect Apple TV to Soundbar "in" with HDMI
2. Connect Soundbar "out" to TV via HDMI
3. Connect Cable Box to TV via remaining HDMI port
4. Connect TV to soundbar via optical cable
5. Connect DVD player to TV using component cables (May not be necessary if I decide to use Computer to play DVDs via Apple TV)
Am I following your advice correctly?
Finally, I am wondering about your thoughts to an article on CNT about using my TV as a switcher. It is below:
Thanks for your patience and help!!
