I have been using Media Center to watch TV for at least 6 months with no problem. I recently "upgraded" my cable to include a set top box so I could watch HBO in HD.
When Media Center searches for a TV signal it can't find one. It then lets me search manually, if I choose cable and say I have a set top box it can find a signal on 3. But then it searches for a IR control cable (which I don't have) I get the message can't detect IR hardware. Then it will not let me continue and save anything.
If I use WinTV 7 from Hauppauge it can find the signal on 3 and it will work. But the picture will not fill the screen there is a 1.5 inch border on each side that stays black.
I had no such problem when I was able to connect my cable directly into my tuner. But with the set top box I get this border.
Of course my cable provider can't help. They even claim that I was not watching HDTV on my computer moniter for 6 months - since they don't support it. I kept telling her that all the local stations came through the cable as QAM and worked great.
I don't think she liked me saying that the HD picture was sharper on the direct cable than through the set top box.
I am also interested in getting a cable card tuner so I can get rid of the set top box but media center says my graphic card isn't good enough - but won't tell me what I need. It seems strange since I am watching HD right now and it works fine and has worked even better without the set top box.
Is there a way to get Media Center to work with the set top box? And what is the requirement for a graphics card to use a cable card?
