[Raak] Sorry, I could have sworn I read your post as saying you intended to connect a disc player. Ignore HDMI cabling entirely.

[Stevie] I thought TVs all ran over HDMI these days? I do have a DVD player (other than my computers), but it and the TV are both so old they use SCART.

[Raak] You said you were going with a network-to-TV model. A smart TV will hunt for your network, ask for a password and then present you with whatever app-based interface it uses so you can start consuming content. No wires other than the power cable. You want to push a signal in over a wire, HDMI is the best way (but not usually the only way on a decent TV). You want to take the sound to somewhere it sounds decent (thin tellies mean small speakers, no resonant cavity and crappy sound) use an optical link (over a cable) to a soundbar for the most compact solution. You can buy a receiver later if you decide you need better sound.

I use wired ethernet for my smugsmart TV; no point in saturating the wireless network on a fixed device if you already have an ethernet drop nearby. It came with a separate WiFi USB dongle, which I repurposed on another machine after discovering it was a rather nice dual-band device based on the Atheros chipset. Netflix is all I use the TV's 'smart'ness for; I have played round with using it as a DLNA client but it's not nearly as nice as using the XBMC box.

I ended up buying a matched soundbar from the same vendor (Panasonic Viera), one that uses HDMI and connects to the ARC-enabled port on the TV, which means basically all three gizmos (HTPC+CEC running XBMC, TV and soundbar) can be controlled with just the TV remote. It also means if I turn off the TV and just use the HTPC/XBMC + soundbar for music, the xbmc mobile app can control the speaker volume.

It's all basically as straightforward and usable as it can get. If I were going to buy a Smart TV again I might get a Samsung or Vizio, as there's a Plex app available for both. Which is a whole nother topic. (I don't use Plex myself but it's what I'd recommend to pretty much anyone I didn't recommend Apple TV to, i.e. someone who doesn't have a houseful of predominantly Apple goodies already.)

[Dan] Yeah, but you are clever.

I avoided the price-attractive Vizio after reading a large number of reviews of later models that suffer from persistent random reboot issues. No point in a smart TV that can't be a TV reliably IMO. The picture on my Father-in-Law's Samsung (dumb) TV is outstanding.

I went Sony only because I have a good experience with Sony products, their tech support was rated higher than everyone else's and they offer four HDMI inputs to everyone else's two. It seemed to me that I'd be bunging wires into it from all over the place and better to find I had too many sockets than too few. I'm also familiar with the Sony video family "quirks" and it seemed likely I would have a better time getting the clown out of the picture.
