If you have any further questions, let me know.

When I used to pull this channel from the wall with a PCTV stick, this is the type of file I was getting. I’d like to replicate this as close as possible. Heck, I’d love to be able to just pull the raw data (whether I stay with my MPEG2 cable provider or switch to DISH). If I do stay with my cable provider, is there a device that offers HDMI MPEG2 encoding that meets or exceeds 15 MBPS?

The device you linked to seemed like it was going to downconvert the audio to 2.0. Will it re-encode the audio or is there a way to capture the data as it is sent out by the receiver?

Ah, but that’s just it. You said you wanted a “lossless” capture method. You have to make a new recording that will capture the audio and put it on a new file, there’s no getting around that. As for the format and channels, while there are devices that capture audio in 5.1 they are all lossy. I know this because I myself have searched high and low for such a device that captures 5.1 sound in LPCM lossless format and it just doesn’t exist in the present time. If you want lossless, you’ll have to stick with 2.0 sound. If you’re willing to chance it on AC3 codecs and you’re not concerned with capturing in 4K, you might want to invest in a Hauppauge, those aren’t bad for $150.
