Hi everyone, I'm planning on building a HTPC for my parents. They just got a 72 inch 1080p HDTV, and I figure I'll help them get the best out of it. My parents subscribe to Cablevision IO, and have a HD box connected to the HDTV. I want to be able to use MythTV to record HD content, provided by the HD cable box. Now I have a few questions. What kind of tuner do I need that will let me record in HD? I see a bunch of tuners that support OTA and QEM encrypted HD, but I'm not interested in that. My parents pay for premium HD content from Cablevision, and I want to use that content. Also, how will I hook up the HD cable box to the tuner card? And finally, will ALL channels the HD box provides be recordable? Thank you!
