Firstly I got a TV that was going to be thrown out in the rubbish due to only one side of the screen working...elbow grease at my garage and it is now my tv then I bump unto a post of all the things you can do with a HTPC lol.
I purchased two tunners at cheap price on trademe then now with WMC in W7 im running the tv, tv3 and tv2 on demand on the big screen and surf the web and even use twitter while watching tv. I love that I can record and watch tv or scheducle while im away.
but one of my favorite parts is I can use skype and google plus+ with just adding a nice webcam to the screen and the most important part I can game on the big screen is flipping awesome specially with the wireless key that keep all tidy.
I nearly forgot to tell you guys that I also made my own HDTV antenna with bits and pieces from the garage and it all works fine with two tunners. I know is not the flashes but I had heaps of fun putting this HTPC. Also I addes some ambience light behind the tv for the movies and lol nice.
The most incredible thing is even my wife can use it without issues and i scored some points there as she never misses a show now.. haha I will see if I can up load some picks of my setup.
