|Hi, I'm not really sure what you are trying to achieve.|
So, I will throw some suggestions at you so you can look into them.
Do you have a network connection on the TV?
Is the TV DNLA compliant?
Do you want to stream TV signals from the internet to the TV?
Or do you just want Media, ie Movies & Music to play on the TV?
I know you don't want a slingbox. I don't really know anything about them.
A Network Media player like a Western Digital can send media from the pc to the TV. But I suppose thats similar to a slingbox.
Have you considered a Media Server on your PC?
That is free.
Wild Media Server http://www.wildmediaserver.com/
Is not free, but I think you can get Youtube, & Hulu if you are in America. Over the network to the TV.
A thank you would be nice, if I have helped.
