We took a look at Meedio and their software last night and it seems to me a good alternative to a Media Center PC, especially if you want to do home automation as well.
Meedio Essentials acts as the home page for your home media, allowing you to view pictures, listen to music, view video, check the weather, and launch applications, and there are lots of add-ins to expand it’s functionality.
Meedio TV is PVR software allowing you to view, record, and time-shift TV. It operates asa standalone program or as a plugin for Meedio Essentials.
Meedio Housebot is a home automation server which works with all the standard home automation hardware such as X10 and powerlinc.
We hope to be reviewing their software in the future, and in the meantine you can get more information at meedio.com
