Is This Possible - HDMI Cable TV to Laptop

[Anyok6]

Is it possible to record an HDMI input from a (comcast) cable box onto a laptop, via HDMI cable? (Without using TV tuner / Capture card?)
If yes, what software would this require?

Essentially I want my laptops HDD to act as a DVR. I understand that laptops picture is being pulled as an output, so does the laptops HDMI port accept input?

It is an Newegg.com - lenovo IdeaPad Y550P(324156U) NoteBook Intel Core i7 720QM(1.60GHz) 15.6" 4GB Memory DDR3 1066 500GB HDD 5400rpm DVD±R/RW NVIDIA GeForce GT 240M

Thanks!

No. The HDMI is an output only port. You would need some sort of USB Video Capture device compatible with Win7x64. But if you were going to do that, you may be better off with a USB TV tuner that can also take a cable TV signal.

Try calling Comcast, or checking your system information manual. I have Dish Network, and they do support this, though its not through a HDMI cable, it's through a USB.
But, most-likely, it doesn't allow you to record onto the HDD, but transfer recorded content already on your DVR onto your HDD, thats how it is with mine atleast.
Rik55 is right - the HDMI port on a laptop is HDMI(video, possibly sound) out only. Not in.
