It is a SR6200....
I had a Tivo HR10-250 and just switched to Directv HR-21...I held out as long as I could because I liked the Tivo interface and heard bad reviews on the Directv box - Everything worked fine with the HR10-250.
Attached is a copy of the response from Marantz after I replied to their first response.

This issue is not unique to marantz receivers. This was an issue all manufacturers were experiencing at the time this receiver was released. Keep in mind this receiver is close to 10 years old and the newer receivers are able to compensate for the errors in Direct TV's audio output.
Unfortunately we do not offer refunds on products, and certainly not products outside of the warranty period.

It is unfortunate that Marantz AUDIO/video receivers are incompatible with the nations largest satellite TV provider with over 18,000,000 subscribers. You can be assured that I will no longer buy audio/video receivers that can't play audio. May I make a suggestion to help potential Marantz audio/video receiver owners:
1. A giant banner on your website that states: DO NOT BUY OUR RECEIVERS IF YOU ARE ONE OF THE 18,000,000 DIRECTV SUBSCRIBERS - OUR EQUIPMENT IS INCOMPATIBLE WITH DIRECTV SATELLITE RECEIVERS. YOU CAN PURCHASE A COMPATIBLE A/V RECEIVER FOR SEVERAL HUNDRED OR EVEN THOUSANDS OF DOLLARS LESS.
I also find your solution of changing the output to pcm unacceptable. The whole point of an audio/video receiver is to play audio. Specifically, 5.1 audio as broadcast from high definition channels - if I wanted to hear my tv in pcm I wouldn't need an audio/video receiver. I would be happy to return my receiver to you in exchange for a full refund so that I may buy a Denon receiver that is fully compatible with Directv. Please let me know where to send my receiver and receipt for what I paid for it. Thank you.
