I have just built a HTPC with a Hauppage HVR-1800 tv tuner. I have a set top box from my cable provider that receives HD channels. My question is can I run my cable from the wall to the STB to the HTPC to the TV. I am familiar with the cablecards but I don't have a slot for this on my PC. I have a SONY BRAVIA XBR4, but I'm not sure if it has a slot. I will find out though. Not sure it would even matter. What is the best way to set up my HTPC so that I can use the VISTA Media Center features (eg. DVR, TV Guide,etc.)I would like get more than just local HD channels through my HTPC.
