Wii Itunes Streaming

Stream Video from PC to TV?
I am looking for the best option to stream video and music from my PC to my TV. The TV has a VGA input, it is a 42″ Plasma/HDTV. I have an extra PC that I could setup right next to the TV to connect. Challenge: I want an easy solution, that will not require me to stream my media to an app like Orb (on the web) to then stream it back to my TV through my Wii. I have looked around on the web and only found solutions, that will require massive PC upgrades and/or purchase of expensive LAN Media Extenders etc.
There has to be an easy way to get this done without compromising video/sound quality! Please!
General setup info: 42″ Samsung Plasma, Comcast digital cable box with DVR, Wii, Spare PC (with iTunes)
Ideal solution: Stream video/music from PC to TV using either LAN or direct connection without purchase of AppleTV, wireless media extenders etc.
The easiest way is to connect the PC to the TV via VGA.
For anything else, you need a digital media adapter.
