How can I connect my HD cable box which is from Comcast with my DVD recorder? I am having HD Comcast Cable Box and a Sony LCD HD TV. I have just bought a Toshiba DR400 DVD Recorder which has HDMI output. Is there any technique using which I can use my PC on my TV? What cables do I require so that this can be possible and how can I connect my cable box to my HD TV? So if anyone having any solution or procedure do post the reply.
