I recently recorded the Obama Inauguration in high defintion 1080i on my Comcast DVR. I want to transfer the video footage to my computers hard drive. Are there any devices that will allow me to do this?

When I had an 8300 I searched high and low but could not find anything on how to do this. From what I gathered, the boxes use a proprietary software/disc format. The only way I read of people getting it to work is by hooking up the box physically to a video card with a video input and playing back the shows through the PC, then using a 3rd party software to record what is being played.
