Multimedia application

I have an old PC that isn't really doing anything so I decided to make it into a multimedia PC for my home entertainment center.  I looked around a little bit to see if there are any freeware applications that will handle this application.  I found Freevo and MythTV.  Both of these applications are Linux based which is ok for some people but I am a .Net developer so I wanted a Windows .Net solution.  I haven't found anything that is written in C# so I decided to start my own for now to see how far I could take it.

Here are some things I want to do

• Play MP3
• Play My Home Videos
• Slideshow pictures
• X10 Home control
• Speech and Voice recognition
• Record TV Shows
• Monitor Home Security
• Get News feed with speech
• Weather reports
• RSS Aggregator
• Internet Radio
• Home Wiki
• Audio/Text Message center
• Allarm clock
• Play Games

I started a Home Automation Wiki Wiki to keep notes on my progress.
