Okay, I thought I should follow up the previous post with something completely different.
This morning I finally got around to integrating my Logitech Revue (a severely under-appreciated tool by the way), with the rest of my home entertainment system. As such I thought I would put down on bits what I have :)
1 x AWA TV (42 inch/1080p capable) - $500
1 x Samsung Sound System (5.1) (2nd hand, around $200 when we got it)
1 x Logitech Revue (GoogleTV) - $90 at the time, prices have gone up since Logitech stopped manufacturing them
1 x Office/Home Entertainment system
Various Consoles (most of which were recieved as gifts with the exception of the XBox 360).
Consoles: The consoles are fed into the AWA TV via an RCA switch, while the audio is directed into the Samsung sound system.
Media Consumption: Most of our media consumption up until now has come via the MythTV setup. It contains all of our media and music. However this morning I finally got around to buying a DVI -> HDMI cable and fed the video from the Myth box into the Logitech Revue. I have also mapped the Logitech Keyboard controller so that the Revue relays all commands to the MythTV IR reciever, which means that I can now control both the Revue and the Myth from the same device.
It's early days yet, but with everything much more centralised, and with direct access to things like Youtube, TuneInFM and other web based media services, we're a lot further along the way to leaving terrestrial tv behind.
