How do you capture/record in mkv with 5.1 sound?

What kind of capture/recorder do people use to capture into mkv with 5.1 sound?

I've never heard of someone capturing directly into an MKV container.

What is your source and what video compression format do you want to end up with? Cable HDTV to H.264?

That is what I'm asking. How do people record HDTV programs in an .mkv format with 5.1 sound? What kind of device to capture it? Do they make a DVD recorder or a TIVO type recorder that does it? Example: someone recorded the Victoria's Secret Fashion show last night and it is in .mkv format, 720Hd, and 5.1 sound. How would they have done that?

They are probably recording digital TV streams directly using a computer tv tuner with hdtv/dvb/atsc support. And then converting or remuxing the ts stream to mkv.

Ok...Makes sense. The computer TV cards must have drastically improved since my all in wonder card. I suppose the cards are digital now and better quality than before.
