I also want to do this, but there are some realities to deal with.
Content providers do not want us to skip commercials as that is thier revenue stream, would you prefer all channels be like HBO, no commercials but cost more? I personally would but I suppose the market isn't there.
Content providers also do not want us to have nice unencrypted copies on our pc that allow the content to now be rebroadcast to many other potential customers for free via the internet (although if you had to watch the commericals in them maybe they wouldn't care so much) .
These issues are understandable to a point, after all the shows you and I like so much are not cheap to create, someone must pay for them.
This leave us in our current situation, that is encryption, and even HDMI has it in the form of HDCP.
Why do we have SD solutions now? Simple the advent of cheap D1 resolution mpeg2 encoders, these things pretty much made the TIVO and pc dvrs exist. Unfortuanately a similar chip but at HD resolution has not surfaced yet with a reasonable price. If it did then you would see component capture cards that do pretty much exactly what the svideo ones do now(no encryption on component).
Sure you can capture HDMI with the card you found, but it will not decrypt HDCP, and even if it could the 119MB/sec is difficult for most drives to handle and that would be a single tuner mind you. They say they can do MJPEG in realtime for 12MB/sec(vs 2.3 MB/sec for the original mpeg2 on the cable line), but I am sure this would tax even a modern cpu to its limits, so forget about re-decoding and watching this video while its being recorded.
From a technical perspective the best solution is to access the original mpeg2/4 stream from the provider but not decompressing it until it is to be displayed, and the only way to do this with a pc currently is with a cablecard or some sort of grey market STB hack like the r5000hd.

I don't mind using a stack of STBs from my cable box to decode the channels, I don't mind paying Comcast for the priveledge of watching TV.
This seems to be the perfect solution to me.... It can capture HD and SD data from my STB. What am I missing that you guys are hesitant about?
WHen you say uncompressed, just how big would a 1 hour tv show be? 8 gigs? hard drive space is cheap ($120 for a 500gig sata drive).
I seem to be missing something here, what is it?
