I found myself in the same circumstances, and discovered that the Cinema7 was able to 'learn' virtually all the functions of the DishPlayer 7200. After having been very disappointed, I'm now very pleased!
The One For All FAQ page has excellent tips on getting the most out of the Cinema7 remote.
[Link: ampersand.hypermart.net]The key is that you *can* assign learned functions to keys other than 1L-4L. As long as you don't have to use 'learning memory' for your other devices, there should be sufficient room for the satellite dish remote's keys.
