oops, too quick on that google search. lol. Apparently there is almost no HDMI/Component capture cards... although i found thishttp://www.blackmagic-design.com/products/intensity/
Captures up to 720p at 60hz. (aka, also does 1080i at 60 or 50hz). This is just fine considering TV doesn't broadcast anything over 720p/1080i. (According to CNET = http://www.cnet.com/4520-7874_1-5119938-1.html
But if i decided to pick up this card, could i get LinuxMCE to recognize it and 'watch' it? the cable box would do all the switching.
(goes back to googling Linux drivers for this card)
OK, another tidbit to note. HDMI carries with it HDCP encoding which i'm sure this card would not have. So, if you pay the extra money to get the pro version (which looks like accepts component input) you can use the Component input to capture HD video with no HDCP encoding. You'd only then have to pair it with the Audio afterwords.
I'm getting the feeling that this is going to cost a LOT of money, and may never work. lol. It just angers me that they designed OCUR and BOCR certifications to not allow DIY systems at all. I mean, if it was just to keep you from back-hacking into the cable systems why don't they take something like ATI's Digital Cable Tuner (with USB output) and allow it to connect to any MCE machine. so it's just a USB-Video bandwidth. BUT, they don't... this sounds way too much like the big companies paid cablelabs to screw the little man.
