Apple TV can connect and browse YouTube. What I needed to do was to update the firmware of the Apple TV. After rebooting, the YouTube menu was up there. So I spent hours browsing through the YouTube site with my login credential. I just hope Apple would come up with more features to browse through sites like this or even the Internet itself. Then the TV and the Internet are really converged.
Now about the sound system connection, Do you still remember what I said yesterday about using the optic fiber to connect to my sound system? My NAD home theatre system gives priority to the sound that connect using the Optic Fiber Cable. That is even if the Apple TV stays idle, my sound processor amplifier do not switch the source to use the input from other video source. Even when I switch off the Apple TV, the light source stays connected. The only way to have my amplifier to play sound from the DVD was to pull off the plug of the Apple TV.
So what I did to my DVD player was I switched the Optical Cable fiber back to connect the DVD to my amplifier, and use the stereo pair monster cable to connect to the Apple TV. By doing this, when I do not use the DVD and switch it off, the sound source will be switched to the stereo cable. This means that for my DVD, the light source is off when the unit is switch off as well. I can then have both units stay connected to the system at all time.
My next trial is to use anothe Optic cable to connect both units to my amplifier. It might not work, but it worth the try so as to know if my amplifier do have precedent setting on both of the optic fiber port.
One thing that I found with the Apple TV is the heat. It rather hot when the unit stays on power for sometimes. I may need a cooling pad/device to help on this.
