I apologize for not being more detailed in my answer. Had you just asked me to clarify what I meant, you would have saved yourself a lot of keystrokes. Also, I shant be offended by your pedantic, catechism of a semi-rant. It is clear there is a misunderstanding. I had presumed you would know what meant by "depends upon satellite, transponder, etc." as most on this board are "techies." However, considering the frustrated tone of your response, I'll attempt to clarify what seems not to be getting through. I'll try to simplify it for you so that you can understand, so please forgive any non-technical, detailed terms. I don't want to confuse you even more:
On the EA, a channel (or even just the East and West feeds of the same channel) may be on a transponder with only 4 other HD channels while on the WA on a different satellite, that very same service may be up-linked to a transponder with 6 other HD channels. Obviously the fewer channels, the more bandwidth for each service channel and more room for higher resolution. So, the very same channel service would suffer somewhat in PQ on the transponder with more channels. It all depends on how much bandwidth is available on the particular transponder and even the sat itself. Most likely the sat at the limits of its bandwidth may have to make do with lower resolution to fit more channels on that sat, and the same for a transponder. That is one way how an East feed of one channel may have different resolution from the West feed. It is all up to Dish as to how they choose to manage the bandwidth of their birds and arc services.
Now, to be sure, that above explanation isn't very technical, but I didn't want you to feel lost, confused, and completely miss the boat on what I meant in my previous and concise reply that confused you so. I hope the above over-simplification helps.
Anyone else if encouraged to explain it better than I have because I know others are better at that than I.
