Alright, I'm currently running a Windows 7 based HTPC which has the specs of a decent sandy bridge based gaming rig. I recently got Comcast cable(Digital Preferred) and have the standard set top box with no DVR since I don't feel like paying $16/mo. The set top box is running via HDMI to my receiver and optical for audio, however that's a limitation of my receiver not being able to handle audio through HDMI. I currently own a PVR-500 and a Fusion HDTV 5 Gold which is installed but I've only used them for OTA signals and never cable.
I'm curious to see if I would need a better card to pick up the signal from the Comcast box. The Comcast box also has the standard coax out but I've been reading a lot about the encrypted signals from a lot of the cable providers and the PVR-500 I believe can only handle 125ish channels according to the white paper. I've been seeing a lot of talk about the Elgato, hauppauge colossus, and the Ceton InfiniTV 4. I have no problem spending around $200 for some of those types of solutions if it means I can use my HTPC as a full DVR with no channel restrictions because of encryption, but most of the articles I see are from people who are trying to bypass the cable box as well. What would you guys/gals recommend?
