I have been following this thread because I had the same problem. I am going to get Hoster, but first I dowloaded the Demo and tried it. When it came time to hook the laptop (HP dv5150us) the display in the TV was B&W. I tried another computer (Dell) and 2 other TVs as well as an RF adapter to take the signal through the cable input of the TV. All gave a B&W picture.
The problem was that I was using a S-video cable that was splitting the signal into video (yellow cable) and color (black cable). This morning I paid a visit to the local MicroCenter and I got a s-video to single male RCA plug. The signal now is beautiful!
Hope this helps.
