The problem with the 811, if I remember correctly, is that it is recmote controllable by RF (UHF) only, not by IR. The specifics of the UHF are proprietory to Dish and are not available to universal remote makers (or they are, and the universal remote makers do not want to dedicate a model specifc to one manufacturer's hardware).
The bottom line is that there is NO after market / third party universal remote capable of controlling anything that only responds to RF remote commands.
Dish's newer HD offerings, such as the VIP series, can be controlled by IR or RF (or both, one per tuner). I personally have a VIP 622 and have been very pleased. I use both a HTM MX-700 and URC-200 to control it in IR mode. I also have it's second tuner output connected to all the "other" TVs in the house, each of which is controlled by a Dish UHF Pro 6.2 or 6.3 remote (the 6.3 is original equipment for the 622, the 6.2 is a slightly over revision, that is 100% compatable with the 622, and probably the 811 as well. They can be purchased at DishStore.net)
