I am very surprised that my searching hasn't been fruitful. I expected such a thing to be easily found.
I have a very old computer sitting around. I wanted to use it as a Media player. It has a CD drive, but no DVD drive. I want to hook up a LCD monitor and my stereo and use it to watch streamed movies and music. I don't want to do a standard OS install and then add the appropriate applications. I want it to be completely dedicated to media with a full-time dedicated interface. Something like a MythTV distro, but not centered around a box that has a TV-Tuner.
If this was a LiveCD, it would be great. I have found many things that come close, but they are all years old and abandoned or focused on emulating a TiVo.
Any thing you folks know of?
