I have the 2250 Media Center kit from hauppauge that is working fine but now comcast is switching to all digital, forcing me to use their dta. Everything is going perfectly in the tv signal setup until I get to configuring the mc remote to change the channels on the stb. I've spent hours repositioning both of the ir blasters over the stb's reciever, even took apart the stb and put the blastres directly onto the reciever but cannot get it work. Please help!
