sd on hd reciever

[DishSubLA]

I doubt that Dish does any HD-to-SD conversion for SD channels--its done by the stations themselves.
The aspect ratio on the 622 series is maintained separately for SD and HD transmissions using the "*" key so you should not have to compromise on that while surfing. A number of channels have adopted letterboxing on their SD channels, when showing material with wide aspects. But then again you can see some SDs that shift from wide-screen style for the titles/credits to pan and scan for the body--hate it.

I think you are correct Ken. It is not a problem for Dish to receive every possible feed from the channels with whom they have agreements, and in some cases it may be better to continue to receive the SD feed to avoid the problems experienced with some digital OTA HD that Dish has to convert. This additional cost is NOTHING to Dish and maintains there mission for the best possible PQ, etc. they can muster. Charlie has never had any problem paying for whatever it takes at the up-link's end to receive the programming and and send it out in the best possible quality for the best possible experience for his customers. Price really is no object there. The only real problem is the bandwidth available on the Dish satellites; that is where all the compromise exists.
